Abstract

The difference between the triplet‐triplet and singlet‐singlet absorption spectrum of naphthalene has been measured at 90°K using a newly developed computer controlled spectrograph. Good spectral resolution has been obtained and a strong band was found in the ultraviolet region. Recent calculations are compared with the triplet‐triplet spectrum of naphthalene.

The triplet-triplet absorption spectra of a number of aromatic molecules were shown to be broadened in low temperature matrices formed by aromatic solvents (toluene, 4kopropylbiphenyl) as compared with those in aliphatic solvents (ethanol, methylcyclohexane, triethylaminc). The effect is exponential
