Abstract

Measurements of benzene concentration based on high-resolution laser absorption spectroscopy by use of the R(6) transition in the ν 4 fundamental vibrational band near 14.8 µm (676.6 cm-1) are reported. These measurements were performed with a tunable continuous-wave, mid-infrared spectroscopic light source that employs difference-frequency mixing of two Ti:sapphire lasers in a GaSe nonlinear optical crystal. A minimum benzene concentration detection of ∼11.5 parts in 106 was realized at a reduced pressure of 40 mbars.
