Homework Help: CHEMISTRY

Posted by Kelly on Friday, March 26, 2010 at 6:50pm.

Hey
1)how do you estimate the line widths (full width half maximum) of the peaks arising from:
(a) The emission of a hollow cathode lamp
(b) The absorption peak of caffeine in the UV –visible spectrum
(c) The d-d transition observed for Ni2+ in aqueous solution

2)Comment on the effects which determine the linewidth in each case. In which case(s) are the observed linewidths likely to be limited by the resolution of the monochromator in the spectrometer itself?
Need help
Thank you
