Publisher Summary This chapter investigates two fundamentally different, yet
complementary routes to computational studies of radical hyperfine structures. The role and …

Despite the highly non-volatile nature of Si, silicon bearing molecules are a significant trace
constituent of the gas associated with late-type stars and star forming regions, representing …

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 …

We have used negative ion photoelectron spectroscopy to measure the electron affinities of
diazocarbene and the diazomethyl radical: EA (Χ 3Σ-CNN)= 1.771±0.010 eV, EA (Χ 2A …

Several structures and electronic states of the C 2 N and CN 2 molecules have been studied
using complete active space SCF (CASSCF), multireference configuration interaction …

Spectroscopic data for triplet isotopomers H− C− C− C− H, H− 13C− C− C− H, and H− C−
13C− C− H are consistent with computational predictions for a symmetric structure in which …

Geometric and vibrational characterization of CCN (X̃ 2 Π, ã 4 Σ−, Ã 2 Δ, B̃ 2 Σ−, C̃ 2 Σ+),
CNC (X̃ 2 Π g, Ã 2 Δ u, B̃ 2 Σ u−), CNN (X̃ 3 Σ−, ã 1 Δ, b̃ 1 Σ+, Ã 3 Π, 1 1 Π) and NCN (X̃ 3 Σ …

Reactions of laser-ablated Pb atoms with CO molecules in solid argon lead to the formation
of the lead carbonyls, PbnCO (n 1–4), using matrix-isolation infrared spectroscopy …

Reactions of silicon atoms and small clusters with carbon monoxide molecules in solid
argon have been studied using matrix isolation infrared absorption spectroscopy. In addition …

Cocondensation of thermally generated silicon atoms with an excess of nitrogen at 12 K
offers an access to new binary silicon− nitrogen compounds. In addition to the well-known …
