Sir in your video on infrared radiations you said that in graph of higher energy radiations we consider frequency whereas in graph of lower energy radiations we consider wave number . But while discussing the graph of uv visible radiations you have taken wavelength on x axis. if uv visible radiations are of higher energy region then we should take frequency on x axis instead of wavelength???..... please clarify

Monochromator converting radiation into single wavelength then how will Recorder plot the graph of so many wavelengths? DO we have to repeat the experiment at all wavelengths?

Same question. I have mine set at 412nm to measure the absorbance of formaldehyde which has been derivatives with acetyl acetone, acid, and ammonium acetate bc formaldehyde by itself has very poor absorbance. I can get an absorbance value for my sample and that’s honestly all I need. But how could I test a standard at a range of wavelengths to get the absorbance vs wavelength plots that determine the maximum absorbance for that compound? Perhaps more advanced machines have variable wavelength tests that measures the whole range? I’d think there’s a method to do this without repeating it hundreds/thousands of times at different wavelengths.

Why the non-conjugated alkenes does not participate in the uv spectrophotometer
@AbdullahSanaUllah3 жыл бұрын
Because the region of wavelength of UV Visible rays they absorb is not provided by uv vis spectrophotometer

I need to see the absorbance of dichloromethane by carbon by using uv visible spectrophotometer. I had already run a pure dichloromethane to full range of uv visible spectrum I e,190 nm-1100nm to see at which wavelength its peak is seen . And,its highest and clear peak have been seen in 208nm. But in literature the range of DCM for uv visible spectrum is 233nm, and highest 274 nm. Somewhere it is written the range is between 200-300nm. And according to 'OECD guidelines for testing of samples' by uv visible spectrum, it's range is 235 nm for dichloromethane. Now I am confused what wavelength range I must fix for my samples. Please guide me.

@@AbdullahSanaUllah you mean to say, we should take any one range between 200-300nm, it can be 235, 274. Or 288 But we have to write like this-The range taken lies between 200-300nm? Am I right sir?

How can you measure your sample/standard at multiple wavelengths? Like you said you measured it using wavelengths between 190-1100nm, do you have to change the wavelength each time or can you measure the whole range without having to go back in and set the wavelength each time? I know the wavelength of what i’m testing is 412nm, so I have it set to that, but i’m curious how I could verify that is my max absorbance wavelength without doing 1,000 tests
