Quartz Spectrograph

The electronic emission and absorption spectra of o-fluorobenzaldehyde have been studied. The emission spectrum recorded on a Fuess glass and a medium quartz spectrograph lies in the region 26 668–17 862 cm−1 and the absorption spectrum recorded on a Zeiss Q–24 medium quartz spectrograph lies in the region 30 995–24 610 cm−1. The O—O band has been observed at 26 337 cm−1. The C=O stretching frequency 1733 cm−1 in the ground state and 1355 cm−1 in the excited state is most intense and forms progressions of bands both in the emission and absorption spectra. The observed bands have been interpreted as combinations of the C=O stretching frequency and its multiples with other fundamentals. The transition involved is A‘–A’ ( n–π*).

Stretching Vibration

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*).
