The triplet--triplet absorption spectrum of naphthalene (3B1, -3B2u; 3A, -3B2u) was calculated using an ab initio method with a S T O -~G basis set and moderately large configuration interaction. Eight bands were found in the region 18,000-45,000 cm-' and compared with those of the experimental spec
The trIplet absorption spectra of pyrazme414 and da III the vapour phase have been remeasured under condltlons which allowed for accurate deternunatlon of transition mtensities No mtrmsic isotope effect on the mtensmes was noted and, III contrast to the smglet absorption spectrum, the big mode qoa I
