Two-and three-photon absorption of 12 is studied in the gas phase. The emission band at ~340 nm is attributed to the 1432, 2g(3II) ~ 2431, 2u(3II) transition, and the 385 nm band to the lg(aH) -, lu(3I]) transition. The 270 and 290 nm bands correspond to states promoted by three-photon absorption.
We report a spectroscopic study of consecutive two-photon absorption of azulene excited in the range 32800-42000 cm-', which provides infcrmntion concerning the cross sections for the S 1 + S3 and the S1 \* Sa traxsitions. \* Eqatum to ref. [4]. S. hiurata has determined Y(S2 + SO) = O.G31-0.032 [S
