Electron-spin-resonance (ESR) spectroscopy has been applied to vanadium, niobium (and tantalum) complexes with N2 and CO in the corresponding pure solid matrixes at 4 K. Except for V(CO)6, none has previously been studied by ESR. For these d,5 S = 1/

The electron-spin-resonance (ESR) spectra of the P3− radical (D3h symmetry) in its X 3 A 2 ′ ground state have been observed in solid neon and argon matrices at 4 K. It is produced during laser-vaporization of solid GaP and is presumably the resu

BH4, with isotopic substitution, has been prepared and trapped in solid H2, D2, HD by laser vaporization of boron and subsequent reaction with the matrix gas. The results confirm the C2v structure of the molecule and generally support the results of

The ions, Ni + , Pd + , Pt + (all having 2 D 5 2 ground electronic states) were produced in the plasma formed during laser vaporization of the metals and directly trapped in solid argon and krypton at 4 K. Electron-spin-resonance (ESR) spectra indica

Laser-vaporized platinum metal, trapped in solid Ne, Ar, Kr, Xe (and Ar, Kr mixture) produced a progression of absorption bands with a spacing of ∼200 cm−1 beginning at 1942 cm−1 in Ne and shifting successively to 1579 cm−1 in Xe. In contrast

Two vibronic transitions, 2Δ3/2(v=0)←2Δ5/2(v″=0) and 2Π3/2(v=0)←2Δ5/2(v″=0) at 923 and 2560 cm−1, respectively, were observed for NiH in solid argon (and krypton) at 4 K. These Ω=3/2←Ω=5/2 transitions were shifted and broadened by m

Ground-state vibrational frequencies of the matrix-isolated B3 and Al3 molecules have been observed. For Al3 there also appears a progression of bands beginning at ≈ 1800 cm−1, which is attributed to absorption to a low-lying electronic state.

Electron‐spin‐resonance (ESR) spectroscopy of these molecules in argon matrices at 2 K reveals that each has a 4∑ ground electronic state, the same as TiV, also containing 9 valence (s+d) electrons. TiTa and ZrTa were not observed. An analogy c
