The microwave spectrum of formamide–water and formamide–methanol complexes

Journal of Chemical Physics, 1988
The microwave spectra of the formamide–water and formamide–methanol complexes have been investigated with a pulsed beam Fabry–Perot cavity Fourier transform microwave spectrometer. The observed hyperfine structure due to the 14N nuclear quadrupole interaction was used to assign the rotational transitions for both species.

Pulse Radiolysis of Formamide and Formamide–Water Mixtures

Canadian Journal of Chemistry, 1971
From the optical absorption spectrum observed by a sub-nanosecond pulse radiolysis method it is concluded that irradiated pure liquid formamide (dielectric constant = 109) does not yield solvated electrons with lifetimes >10−11 s. In formamide–water mixtures the hydrated electron is formed in low yield and the position of the absorption band of eaq−

The conformation of formamide

Journal of Molecular Spectroscopy, 1987
Abstract A reanalysis of vibration-rotation spectral data of formamide using the semi-rigid-bender technique adopted for unsymmetrical 1 large-amplitude motions (LAM) reveals that formamide has a very shallow single-minimum inversion potential. During inversion the amino group rotates around the CN bond with the syn -hydrogen staying closer to the ...

Electric-dipole moments of H2O-formamide and CH3OH-formamide

Journal of Molecular Structure, 1988
Abstract Electric-dipole moments have been determined for H 2 O-formamide and CH 3 OH-formamide by pulsed-nozzle Fourier-transform microwave spectroscopy. For H 2 O-formamide μ a =1.050(1) D and μ b =2.135(3) D while for CH 3 OH-formamide μ a =1.066(1) D and μ b =2.091(2) D. The corresponding complexation-induced moments are estimated as 0.55

BSSE‐corrected geometry and harmonic and anharmonic vibrational frequencies of formamide–water and formamide–formamide dimers

International Journal of Quantum Chemistry, 2005
AbstractThe basis set superposition error (BSSE) influence in the geometry structure, interaction energies, and intermolecular harmonic and anharmonic vibrational frequencies of cyclic formamide–formamide and formamide–water dimers have been studied using different basis sets (6‐31G, 6‐31G**, 6‐31++G**, D95V, D95V**, and D95V++**).

Imidazolsynthesen mit Formamid (Formamid‐Reaktionen, I. Mitteil.)

Chemische Berichte, 1953
AbstractAus α‐Oxy‐, α‐Halogen‐, α‐Amino‐ und unter reduzierenden Bedingungen auch aus α‐Isonitroso‐ketonen entstehen mit Formamid 4.5‐substituierte Imidazole. Formamid dient im Überschuß gleichzeitig als Lösungsmittel.
