Interstellar ices are chemically processed by ultraviolet (UV) radiation to form complex
products, and models of UV photochemistry provide powerful tools for the interpretation of …

Shifts in the ground-state vibrational fundamental frequencies of diatomic and small
polyatomic free radicals, molecular ions, and other short-lived molecules upon trapping in …

The photochemical effects of the interstellar radiation field on the ice mantles of molecular-
cloud dust grains are investigated by means of laboratory simulations. The apparatus and …

The 3 molecules carbonylsilene, SiCO, and diazasilene, SiNN, have been prepared by the
vaporization and reaction of silicon atoms with N2 or CO and trapped in various matrices at …

Laser evaporation of carbon-rich uranium/carbon alloys followed by atom reactions in a
solid argon matrix and trapping at 8 K gives weak infrared absorptions for CUO at 852 and …

Rotational spectra of CnO with n 2, 4, 6, and 8 have been observed by using a Fabry–Perot
type Fourier-transform microwave spectrometer cooperated with a pulsed discharge nozzle …

The photoelectron spectroscopy of a number of radical anions has been investigated. We
find the following electron affinities: EA (C3)= 1.981±0.020 eV, EA (C3H)= 1.858±0.023 eV …

The free radical HCCN was produced in an Ar matrix via photolysis of its precursor
diazoacetonitrile, NNCHCN, with radiation of wavelengths longer than 350 nm. The ir …
