✦ Synopsis

We report the measurement of the absorption profile of the serenth harmonic of the C-H stretch in Iiquid benzene by a pulsed dye laser opto-acoustic technique. The absorption peaks at 18808 cm-' (5316 A), xirh rt peak absorption coefficient being 4.5 X LO4 cm-r_ The asqmrnetric~l absorption proftie has a full \cidth at half maGnum of 317 cm-'_ The systematic trends of the series of harmonic absorption lineshapes in benzene, m the liquid. and In the vapor phase. are dis-

The rovibrational overtone spectrum of propyne-d 3 (CD 3 -C≡C-H) in the region of the second overtone of the acetylenic C-H stretch (3ν 1 ) was monitored employing photoacoustic laser absorption spectroscopy. Comparison of the observed spectrum with that simulated for a symmetric-top molecule reveal
