Abstract
The n–π* electronic emission and absorption spectra of p-fluorobenzaldehyde have been studied in vapor phase. Its Raman and infrared spectra have also been recorded. The spectra have been analyzed in terms of several ground and excited state fundamental vibrations. The C=0 stretching vibration is quite intense and dominates both the spectra. The transition has been ascribed to either A′-A′ or A′-A″ (n–π*).
