91. Phenyl Ring Torsion and Excitonic Interaction in Diphenylmethane
Jaime Stearns, Aloke Das, Talitha Selby, Timothy Zwier, David F Plusquellic
Resonant two-photon ionization (R2PI) and dispersed fluorescence (DF) spectroscopy are used to examine the role of torsional motions in the electronic structure of diphenylmethane (DPM) near the exciton split S1 and S2 origins at 266 nm. Three of th ...
92. Probing S1 Relaxation Mechanisms in 2-Chloronaphthalene via Nuclear Quadrupole Interactions
David F Plusquellic, F - Jahanmir
Rotationally resolved S^d1^ S^do^ fluorescence excitation spectra of 2-chloronaphthalene (2CIN) are measured using a newly constructed UV laser/molecular beam spectrometer. More than 1000 well-resolved rotational lines are recorded for the two overla ...
93. Submillimeter and THz Detection of Dimethyl Methyl Phosphonate in Air
NIST Interagency/Internal Report (NISTIR)
Vyacheslav B Podobedov, R J Lavrich, T M Korter, Gerald T Fraser, David F Plusquellic, A C Samuels
Experimental measurements and theoretical calculations were performed to assess the potential for using continuous-wave submillimeter and THz (far-infrared) linear-absorption spectroscopies to detect chemical-warfare agents in air at ambient temperat ...
94. User Guide to JB95.exe Spectral Fitting Program v1.02.4, 1/30/01 http://physics.nist.gov/SpectralFitGUI
David F Plusquellic
A graphical user interface computer program based on a Windows95 API platform has been written in the C programming language to aid in the rotational analysis of complex molecular spectra. Dialog boxes provide a user interface for the calibration, ...
