Characterizing Chemical Composition of DOD-Prescribed Burns

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Timothy Johnson
Expand the PNNL gas-phase infrared reference library incorporating those species that are relevant to prescribed burns and suggest themselves plausible to infrared analysis. The expansion in…

High Resolution Infrared Spectroscopy of trans-Hexatriene

Lead Institution
Oberlin College
Principal Investigator
Norman Craig
Project type
Exploratory Research
We will record and analyze the high resolution infrared spectrum of trans-hexatriene. The purpose of this work is to determine the structure and vibrational force field of this molecule.

Infrared Spectra of the Fundamental Bands of 34SO2

Lead Institution
National Institute of Standards and Technology
Principal Investigator
Walter Lafferty
Project type
Exploratory Research
Thanks to advances in technology the abundance of sulfur dioxide in urban air has been greatly reduced during the last several decades. The infrared spectrum of the bands of the most abundant …

High Resolution Spectra of Phosphine in the 1370-800 Wavenumber Region

Lead Institution
Jet Propulsion Laboratory
Principal Investigator
Linda Brown
Project type
Exploratory Research
The absolute cross sections of the rotational-vibrational lines of phosphine in the 1370-800 wavenumber region will be studied for identification in planetary atmospheres. The use of the PNNL high…

High Resolution Fourier Transform Infrared Spectroscopy Studies of Multidimensional H Transfer in Tropolone/Tropolonoid Molecules-a Bridge to the Behavior in Biological Systems

Lead Institution
Texas Technical University
Principal Investigator
Richard Redington
Project type
Large-Scale EMSL Research
In the year 2000 high resolution infrared spectroscopy experiments conducted in EMSL at PNNL were initiated on the nonrigid gaseous tropolone molecule (2-hydroxy-2,4,6-cycloheptatrien-1-one). On the…
