Performance of a Fast Response Agent Concentration Meter

May 2, 2000
Author(s)
Erik L. Johnsson, George W. Mulholland, Gerald T. Fraser, A Zuban, I I. Leonov
There is a need for monitoring the concentration of potential halon replacement chemicals with millisecond response time [I]. One scenario of great concern to the Air Force is the penetration of an enemy shell into the fuel tank of an aircraft. To prevent

The Infrared Spectrum and Internal Rotation Barrier in HF--BF 3

May 1, 2000
Author(s)
K Nauta, R E. Miller, Gerald T. Fraser, Walter J. Lafferty
The rotationally resolved infrared spectrum of the HF stretch fundamental in combination with one quantum of internal rotationexcitation has been observed for the HF--BF 3 complex using a color-center-laser optothermal molecular-beam spectrometer.This

Rotational Spectra of Four of the Five Conformers of 1-Pentene

April 1, 2000
Author(s)
Gerald T. Fraser, L H. Xu, R D. Suenram, C Lugez
The rotational spectra of four of the five expected conformers of 1-pentene, together with their monosubstituted 13C isotopic forms, have been measured in a molecular beam using a pulsed-nozzle Fourier-transform microwave spectrometer. One of the

Rotational Spectra of Seven Conformational Isomers of 1-Hexene

February 1, 2000
Author(s)
Gerald T. Fraser, R D. Suenram, C Lugez
The rotational spectra of 7 of the expected 13 conformational isomers of 1-hexene have been measured and assigned at a rotational temperature of 1 symmetry, as verified by the observation of a, b, and c-type electric-dipole transitions. The remaining

Rotational Signatures of Chemical Agents and Related Compounds

January 1, 2000
Author(s)
R D. Suenram, Angela R. Hight Walker, Gerald T. Fraser, David F. Plusquellic, R S. DaBell, Pamela M. Chu, George C. Rhoderick, A C. Samuels, J O. Jensen, Pavol Krivosik, J M. Lochner
The rotational spectra of more than twenty different chemical-warfare agents, precursors, and decomposition products have been studied using the technique of Fourier-Transform MicroWave (FTMW) spectroscopy. The compounds studied include the four common G

Absolute Intensities for the O 2 1.27 ym Continuum Absorption

December 1, 1999
Author(s)
B Mate, C Lugez, Gerald T. Fraser, Walter J. Lafferty
Collision-induced absorption coefficients for the 1.27 υm band of O 2 have been measured at a resolution of 0.5 cm -1 and an optical pathlength of L = 84 m using a Fourier-transform spectrometer and 2 m long White-type multipass absorption cell. Spectra

Pendular States of Highly Vibrationally Excited Molecules

April 1, 1999
Author(s)
J Ortigoso, Gerald T. Fraser, Brooks H. Pate
The behavior of coherent field-induced hybrids of field-free rotor states (pendular states) is studied in energy regions where intramolecular vibrational energy redistribution phenomena are important, is studied. The energy region corresponding to the 4Ņ 1

The Rotational Spectrum of Ar-SiH 4 and Ar--SiD 4

January 1, 1999
Author(s)
Y Kawashima, R D. Suenram, Gerald T. Fraser, Francis J. Lovas, Katsuya Hirota
Microwave spectra of Ar-- 28SiH 4, Ar-- 29SiH 4, Ar-- 30SiH 4, and Ar-- 28SiD 4 have been recorded using a pulsed-molecular-beam Fourier-transform microwave spectrometer. The K = 0 and K = 1 components of the J=3
