Mossbauer Spectroscopy - Spin Crossover II Very Important II

A highly useful and important topic.

[@Rima4246]

Now the spin crossover concept is clear ..thank you sir

[@niteshkumar-mf3dz]

U are the best sir, the way u explain the things is really awesome.

[@umendrakhokhar7114]

thanks sir one again you taught a very important concept in a nice way as always.

[@nilofarmehandidesigns757]

Thank you sir .It's quite useful and very simple explanation for understanding

[@shivikhurana111]

Very Well explained :) stay blessed.

[@gopalkrishnaniyogi7281]

Outstanding sir.

[@deekshasaini9607]

u make this topic easy n simple ...

[@manjutmanjut2966]

thank you sir its really useful

[@arminderkaur6574]

Well explained sir

[@supriyabodake4366]

you mak mossobar very easy thanks ......

[@priyapriyu8435]

Very nice sir thank you

[@gautomigogoi6331]

Very very thank you sir. I also want to know what is the other factor for spin crossover rather than change in spin state? Is there any change in coordination number of the ligand or change in isomerisom or change in metal ligand bond distances?

[@chemysteryassets]

so effective video :)

[@jagatthakur7245]

Nice one sir make a video on electrons for 18e rule ligand chart videos

[@sudheer2643]

Thanks a lot sir

[@sofiagupta1506]

Thanks sir 🤗

[@kironhazarika8547]

Thank u sir....

[@jagatthakur7245]

Thnk u sir

[@sapnabarad2739]

sir could you make a video on magnetic splitting in Mossbauer spectro ?

[@kironhazarika8547]

sir which book or lecture is usefull for Asymmetric synthesis

[@chemysteryassets]

brother if u dont mind , can u briefly explain magnetic splliting in mossbaeur spectro

[@pgboy5149]

sir ..in June question...they have given 3 types of splitting of line based on high , moderate n low temperature...n also..some concepts of CIS trans ...so PlZ sir give ans with explaination .. thank you

[@zpluschemistry9380]

nice video

[@sanjuktamishra7930]

Thanks sir

[@animeshmukherhee7036]

Thnx sir.... Sir which book covers all the topics of mosbaur and esr spectroscopy

[@ankita5640]

thanks

[@suryabhanuprakashgoud1413]

Tq so much sir

[@nilofarmehandidesigns757]

Sir please make a video on perturbation theory and variance method..... I kindly request you

[@nargisjafriofficial]

Very nice explanation...Thank you.I have one question from June 2016: To record Mossbauer spectrum of Fe containing samples, a source 'X' is used.(X) after a nuclear transformation (Y) gives gamma radiation used in Mossbauer spectroscopy.X & Y respectively are : a) 57 Fe, beta emission b) 57 Co, beta emission c) 57 Co e- capture d) 57 Fe, e- capture

[@nargisjafriofficial]

Ok.. thank you

[@harishkumarharit8960]

Answer should be d

[@han-rw1bg]

Can anyone explain why is [Fe(phen)2(NCS)2] complex is taken as high spin even strong field ligand phen is present there ? so overall complex should be in low spin !!!

[@han-rw1bg]

And what is the geometry of [ Fe(CN)4]2- Acc. To VBT, hybridization comes out to be dsp2 so it should be square planar but sir taught tetrahedral. I'm confused. Anyone can clear this please

[@subratrout2091]

I have the same doubt.If it is dsp2 then its configuration should be t2g(5) eg(1) & it will be no longer symmetrical . I think sir told a hypothetical complex...

[@simran1999]

Sir NCS is a strong field ligand whereas SCN is weak field i think...??

[@kanikalalit1153]

NCS seems to be a strong field ligand??

[@enakshisharma5442]

thnx sir plz provide some videos on quantum chemistry

[@enakshisharma5442]

ok sir

[@ucdiaries8064]

please explain instrumental methods of analysis: mass spectroscopy,ir,nmr..etc all types of spectroscopic methods .please please sir,its my humble request

[@bhawanasaklani4802]

nice explanation...but still unable to figure out June 2017 Q related to this .. reason of four peaks only at 186 K....??

[@bhawanasaklani4802]

+Gate chemistry Thanks a lot...

[@jaishrichopra865]

Really love the way you teach..it's always informative and quite different from other tutorial. Thank you for providing such good videos.

[@rachnajoshi1567]

Sir unit conversion m vdo banayega plz.

[@prajaktakadam5974]

Mossbauer spectra of FeCO5, Fe2CO9 & Fe3Co12 shows how many lines????

[@prajaktakadam5974]

Ans is doublets for first 2 n doublet n singlet for 3rd but how?

[@sapnabarad2739]

sir ..mossbauer spectra for Fe3(Co)9 and [HFe3(Co)11 CNme2] ... sir i have notes for this but answers are not there ...

[@sapnabarad2739]

ok SIR ..

[@chetnahasija9975]

In all the examples discussed whenever splitting occurs we have seen 2 peaks but there are certain spectra that show 4 peaks also.please explain how we get 4 peaks.

[@ranitram1728]

The splitting or no. of peaks depend on I-value of the nuclei, if it's I=5/2, bcz quadruple splitting, no. of peaks would be 4 (e.g. : NiX4(-2).

[@chetnahasija9975]

@@ranitram1728 hey thanks

[@as-bw6sr]

Apko vahi milega jo hume deneka sochre ho bhaijaan

[@prajaktakadam5974]

Its ans is doublet for first 2 n doublet n singlet for 3rd. But how?

[@dhikshasharma8960]

Again u have taken td example......and once again u r considering low spin and high spin.......in td only high spin is considered nd electrons are filled in e2 first......plzzzzzzzzzzz explain the td example ......nd also briefly explain this csir june 2017 question...by telling all resons ...coz in the question four lines are also observd......plzzzzzzz help us out..............

[@sarojagrawal9279]

yes sir I m also curious to know it.

[@afjalurrahman2157]

If I am not wrong , phenanthriline is bidented ligand .so the iron complex is octahedral not tetrahedral .

[@afjalurrahman2157]

*phenanthroline

[@dinabandhudas8450]

sir i need your e-mail...

[@shikhadhakar3296]

Why high spin??

[@madness7537]

Nice to learn sir, thank you.

[@vandana9628]

Thanks sir
