Hey.
Im stuck on a question from Salters Chemical Ideas. (Question 1, section 6.4 on page 141).

The question is:

The infrared spectrum of carbon dioxide shows a strong absorbtion at 2360 cm-1.
Calculate the wavelength of the radiation absorbed. Give your answer in µm.


Any ideas? Cheers

kk you got the absorbtion at 2360 then take a reciprocal (divide one by it) and get wavelength in cm...then to convert it to meters divide by 100 and to convert it to micrometers, multiply by a million

4.237µm
