Abstract

A TiCl4/He plasma is observed by high resolution double-modulation FTS using concentration-modulation as a selective detection method. Analysis of the C4Δ-X4Φ Δv=0 transitions of 48Ti35Cl reveals perturbations affecting the C 4Δ1/2 sub-state.

Abstract

High sensitivity spectra are obtained around 9500 cm-1 from a semi-conductor Vertical-Cavity-Surface-Emitting Laser (VCSEL) intracavity absorption experiment. Line intensity measurements on the ν3 band of C2H2 and unstable molecules transitions detection are discussed.
