“…[51][52][53][54][55][56] Our observed jet-cooled linewidth is comparable to, but narrower than, that seen in those previous studies. The estimated FWHM is broader than transitions associated with the room temperature background sample.…”

Lett.Sensitive trace gas detection with cavity enhanced absorption spectroscopy using a continuous wave externalcavity quantum cascade laser Trace gas measurements using optically resonant cavities and quantum cascade lasers operating at room temperature J. Appl. Phys.A new instrument has been constructed that couples a supersonic expansion source to a continuous wave cavity ringdown spectrometer using a Fabry-Perot quantum cascade laser ͑QCL͒. The purpose of the instrument is to enable the acquisition of a cold, rotationally resolved gas phase spectrum of buckminsterfullerene ͑C 60 ͒. As a first test of the system, high resolution spectra of the 8 vibrational band of CH 2 Br 2 have been acquired at ϳ1197 cm −1 . To our knowledge, this is the first time that a vibrational band not previously recorded with rotational resolution has been acquired with a QCL-based ringdown spectrometer. 62 transitions of the three isotopologues of CH 2 Br 2 were assigned and fit to effective Hamiltonians with a standard deviation of 14 MHz, which is smaller than the laser frequency step size. The spectra have a noise equivalent absorption coefficient of 1.4ϫ 10 −8 cm −1 . Spectral simulations of the band indicate that the supersonic source produces rotationally cold ͑ϳ7 K͒ molecules.

The structure and fluxional behavior of (η4-butadiene)Fe(CO)2L (L = CO, PH3, PMe3) complexes have been studied using density functional methods. For (butadiene)Fe(CO)3, the geometry obtained is in excellent agreement with the gas-phase experimental data. The calculation of the harmonic vibrational frequencies has permitted the reassignment of several frequencies observed in the IR and Raman spectra. The computed Fe−butadiene binding energy is in all cases about 52 kcal mol-1, in excellent agreement with the experimental data corresponding to the (butadiene)Fe(CO)3 complex. The nature of the bonding has been analyzed in terms of steric and electronic interactions. The butadiene−Fe rotational barriers have been computed, and the origin of the barrier has been discussed.

“…Lead salt diode lasers have been used to collect high-resolution gas-phase spectra of large molecules [2][3][4][5][6] and clusters [7][8][9] in supersonic expansions. Further development of lead salt diode laser spectrometers is stymied by their limited frequency coverage, low output powers, poor beam quality, and cryogenic operation.…”
