Which of the following types of transition would require the shortest wavelength

Question

Which of the following types of transition would require the shortest wavelength radiation? Rotational transitions Vibrational transitions Electronic transitions A molecule which has absorbed a photon of energy in the visible range could move from the excited electronic state S_1 to a highly excited vibrational level of the ground state (S_0) with the same energy. This process is fluorescence. internal conversion. intersystem crossing. Compared to the incident (exciting) radiation, fluorescent emission will have a higher energy. higher frequency. longer wavelength.

Explanation / Answer

(13) (c) Electroninc transition require higher energy (shorter wave length) than vibrational and rotational transitions.

(14) (a) Fluoroscene (S1 to S0)

(15) (c) Longer wave length
