✦ Synopsis

The S, population decay times of azulene and 4,6,8-trimethylazulene have been measured in solvents with a wide range of viscosities using a two-photon, two-color, pump-probe method. The S, lifetimes vary as expected on the basis of the energy gap law. No effect of solvent viscosity is observed, contrary to a previous suggestion. Data for 2-chloroazulene in non-viscous solvents are also reported.

A mode-locked dye laser is used to generate the S+J TPF pattern of azulene and some of its derivatives. Since none of the patterns shows a Iarger width at half maximum than the one obtained with dimethyl-POPOP, a lifetime of less than 1 ps has to be postulated for 'the excited vlbronic levels Sr,, o

## Abstract The addition of iodine to pyridine not only causes appreciable changes in the ^13^C chemical shifts but also a marked reduction in spin‐lattice relaxation times. The effect at the γ‐carbon is larger than at the α‐ and β‐carbons. This is consistent with the formation of a pyridine‐iodine
