Abstract A supersonic-free-jet infrared spectrometer has been constructed for investigation of molecular vibrational spectra at low rotational and vibrational temperatures. The sensitivity of measurement in a pulsed jet is increased by employing a phase-sensitive detection method synchronized with the pulse frequency. The performance of the spectrometer is examined for the absorption lines of the NH3 v 2 band. A rotational temperature as low as 16K is attained when seeded in He. Cold-jet spectra are demonstrated for thev 3 bands of PF5,34SF6, and182WF6.
