Journal ArticleDOI
Experimental and Theoretical Investigation of Simple Terminal Group 6 Arsenide As≡MF3 Molecules
TL;DR: These molecules are identified by comparison of the closely related infrared spectra of the analogous phosphide species and with frequencies calculated by density functional theory and multiconfigurational second order perturbation theory (CASSCF/CASPT2).
Journal ArticleDOI
A chemical ionization source of molecular ions for matrix-isolation spectroscopy
Jale Hacaloglu,Lester Andrews +1 more
TL;DR: In this article, a chemical ionization source from mass spectrometry was modified for matrix isolation spectroscopic studies, and the results showed that negative ion studies with chlorine gave the Cl2− and Cl3− anion absorbing at 340 and 253 nm, respectively, whose relative intensities depended on source pressure.
Journal ArticleDOI
Reactions of Laser-Ablated Ga, In, and Tl Atoms with Nitrogen Atoms and Molecules. Infrared Spectra and Density Functional Calculations of GaN, NGaN, NInN, and the M3N and MN3 Molecules.

Journal ArticleDOI
Infrared Spectra of the HAnX and H2AnX2 Molecules (An=Th and U, X=Cl and Br) in Argon Matrices Supported by Electronic Structure Calculations
TL;DR: The new molecular products of the reactions of laser-ablated U and Th atoms with HCl and with HBr, namely HUCl, HUBr and HTh cl, HThBr, based on their mid and far infrared spectra in solid argon, are reported.
Journal ArticleDOI
Infrared Spectra of CH3CN→M, M-η2-(NC)-CH3, CH3-MNC Prepared by Reactions of Laser-Ablated Fe, Ru, and Pt Atoms with Acetonitrile in Excess Argon.
Han-Gook Cho,Lester Andrews +1 more
TL;DR: The Pt to N bond in CH3CN→Pt is the strongest of all the metals the authors have investigated owing in large part to its higher electron affinity, which prevents nitrogen lone pair density from entering the pi* orbitals of the C-N group.
