Respuesta :

C.n=2-n= 3 is  the following electronic transitions causes the absorption line at the shortest wavelength.

What transition is responsible for the shortest wavelength absorption line?

The relationship between energy and radiation wavelength is inverse. The largest energy shift, and hence the shortest wavelength, x nm, would occur during the transition from the highest to the lowest energy levels.

The wavelength of the radiation to be used for the measurement is a crucial factor. Keep in mind that the absorbance increases with increasing molar absorptivity. This also implies that the concentration of species that still produces a quantifiable absorbance value decreases with increasing molar absorptivity.

As the degree of delocalization increases, the maximum absorption shifts to longer wavelengths.
