✦ Synopsis

The first excited triplet state of dimesitylcarbene has been generated in solution at room temperature. It has a lifetime of 60 ns and shows fluorescence with A mp~ = 501 nm and absorption with A,,. = 360 nm. This species is quenched by oxygen and carbon tetrachloride with rate constants of (4.4kO.8) x 10" and (7.3f0.6) x lo9 M-' s-l, respectively.
