✦ Synopsis

The photoacoustic overtone spectrum of monochloroacetylene (monochloroethyne, HCCCl) has been recorded in the wavenumber region 9500-14400 cm -' with a titanium: sapphire ring laser. The spectrum shows several vibration-rotation band systems of which 3v, + v2 and 4v, have been recorded with Doppler-limited resolution. Many overtone and hot bands belonging to 35C1 and 37C1 species have been analyzed rotationally. Some of the observed bands show rotational perturbations. Two of these bands have successfully been interpreted as a Fermi resonance pair.

A titanium: sapphire ring laser has been used in intracavity experiments to obtain high-resolution photoacoustic overtone spectra of monofluoroacetylene in the wavenumber region 12200-I 3800 cm-'. The spectra obtained show very large signal-to-noise ratios ( > 1000) for strong absorption peaks. Two

The \(v_{1}+3 v_{3}\) band system of natural acetylene has been recorded with Doppler-limited resolution using a titanium:sapphire ring laser together with a intracavity photoacoustic detection method. The \(v_{1}+3 \nu_{3}\) band appears by far as the strongest feature in the spectrum but there are
