Phosphorescence spectra of <I>p</I>-fluorobenzaldehyde have been observed in (i) the vapor phase at room temperature and in (ii) methylcyclohexane and (iii) methyl benzoate matrices at 4.2 K. From the vibrational analysis and deuteration effect it is established that the phosphorescent state is nπ<SUP>*</SUP> in cases i and ii while it is ππ<SUP>*</SUP> in case iii. A close similarity between the vapor phase emission spectra of <I>p</I>-fluorobenzaldehyde and benzaldehyde leads us to the conclusion that the substitution of the fluorine atom for the para hydrogen atom of benzaldehyde has little effect to the both triplet states. Several experimental data for low frequency vibrations in the excited <SUP>3</SUP><I>n</I>π<SUP>*</SUP> state will be given by analyzing hot sequence bands of the vapor phosphorescence spectrum.
