Question

the extinction coefficients for N-methylcyclohexanamine is 506.7 l/(mol*cm) i ethanol as solvent and lamda(max) is 200.5 nm at absobance 1.034.

Comment on the ektionscoefficient

Which electronic transitions are possible and why?

Answer 1

extinction coeffiecient also called as molar absorptivity coeficient. absorbance directly perportional to the extinction coefficent at given concentration ,pathlenght, and specific wavenghth.

it can repreasented by , it can caliculated by using following formula = A/CxL

where A= absobance, C= molar concentration, L= path length in cm.

in given molicule two types of elecron transitions are possible. there are * and n*

C-C corresponds to * transtions and N-C corresponds to n* transitions, loann pair of nitrigen involves in this transition.
