Alpha is a constant depending upon the spectroscopic ground state. For S state, alpha=0(d5) For D state,( d1,d4,d6,d9), alpha=2 For F state(d2,d3,d7,d8), alpha =4

For all those who are confused about the alpha value, plz note that, If Eg orbitals are assymetrically filled then alpha will be 2, and if Eg orbitals are symmetrically filled then it will have value 4. Now if T2g is assymetrically filled then we will use spin orbit coupling formula.

Thankyou Sir! but I wanted to know about low spin complexes, why term symbol remains same in uncomplexed and complexed forms of metals, like why we relate any complex with free electronic d configuration and determine the term symbol likewise because the concept that orbital magnetic moment in a complex form is to the tone of 1 is violated like that, such kind of question was asked in Gate 2016 I think, and this time's csir net
@AllBoutChemistry6 жыл бұрын
Yes you're correct that we have to consider whether the complex is high spin or low spin while determining the Term Symbol. Now luckily the complex here was a high spin complex so it was pretty simple. But yes when a complex is given and you're asked to calculate term symbol then obviously you've to consider the high spin or low spin nature of complex. The question you're talking is solved here by me, you can watch the explanation by clicking this link: kzbin.info/www/bejne/oWHEeJafe9Osnas

Sir why t2g unsymmetrically filled orbital shows orbital contribution..And why not eg unsymmetrically filled??
@AllBoutChemistry6 жыл бұрын
Very nice question, for involvement of orbital contribution in magnetic moment we need a non spherical environment. Now if you've watched my previous videos you must know that eg orbitals lie on the axes resulting in spherical environment whereas the T2g lies between the axes and spherical environment will be there unless and until it is symmetrically filled, if not then the environment becomes non-spherical. In case of eg orbitals if it is assymetrically filled then also as it lies on the asis the sphericality or you can say uniformity in the electronic environment stays.
@shaswatvikramgupta6 жыл бұрын
All 'Bout Chemistry ...That is in case of eg orbitals there always will be spherical environment irrespective symmetrical or unsymmetrical filling of orbitals.
