21. Experimental Line Parameters of the Oxygen A-Band Using Frequency-Stabilized Cavity Ring-Down Spectroscopy
Topic: Remote Sensing
Published: 1/1/2008
Authors: D J Robichaud, Joseph Terence Hodges, Linda R. Brown, D Lisak, Piotr Maslowski, Charles E Miller
Abstract: Line intensities, self- and air-broadened linewidths, pressure-induced shifts, and collisional narrowing coefficients were measured from 18 <= J' <= 32 in the P branch of the O2 A-band (12,975 13,055 cm^(-1)). Spectra were recorded using the freque ...

22. Semi-Classical Line Shape Models of Rovibrational H2O Spectra Tested Using Frequency-Stabilized Cavity Ring-Down Spectroscopy
Topic: Remote Sensing
Published: 6/20/0008
Authors: Joseph Terence Hodges, Daniel Lisak, R. Ciurylo
Abstract: In this work we present a brief review of recent results for water line shapes obtained by means of the frequency stabilized cavity ring-down spectroscopy (FS-CRDS) technique. We demonstrate its ability to enable precise spectroscopic measurements o ...

23. High-Precision Pressure Shifting Measurement Technique Using Frequency-Stabilized Cavity Ring-Down Spectroscopy
Topic: Remote Sensing
Published: 1/1/0008
Authors: D J Robichaud, Joseph Terence Hodges, D Lisak, Charles E Miller, Mitchio Okumura
Abstract: We describe a high-precision method for measuring pressure shifting of absorption lines. The technique involves the acquisition of high-resolution spectra using a cavity ring-down spectrometer whose length is continuously locked to a frequency-stabil ...

24. High- Resolution Cavity Ring-Down Spectroscopy Measurements of Blended H^d2^0 Transitions
Topic: Remote Sensing
Published: 1/1/0007
Authors: D Lisak, Joseph Terence Hodges
Abstract: We probed four closely spaced rovibrational water vapor absorption transitions near wavenumber = 7100 cm(^-1) using frequency-stabilized cavity ring-down spectroscopy. Room-temperature spectra were acquired for pure water vapor in the Doppler limit a ...

25. High-Resolution Cavity Ring-Down Spectroscopy of H216O at 10687.36 cm-1
Topic: Remote Sensing
Published: 2/11/0004
Author: Joseph Terence Hodges
Abstract: We describe a frequency-stabilized cavity ring-down spectroscopy apparatus enabling high-resolution line shape measurements of water vapor. The measured line strength and broadening parameter for the H216O transition at 10687.36 cm-1 are compared to ...
