The designation for the angle of rotation of the α-carbon–nitrogen bond is ϕ, whereas that of the α-carbon–carbonyl carbon bond is ψ. Although theoretically an infinite number of ϕ and ψ angles are possible around single bonds, only a limited number of ϕ and ψ angles are ...
Ab initio and equilibrium bond angles. Structures of HNO and H2O2StructureAngleAb initioThe possibility of calculating accurate ab initio bond angles is examined using a sample of 29 molecules (35 independent angles) containing only first row atoms and whose equilibrium structures are known. Three ...

Electron deficient compounds • Diborane • Electron deficiency in BeCl2, BeH2, and AlCl3 • Bond angle • Bond length BOARDS MAIN Electron Deficient Compounds Compounds that have an insufficient number of electrons to complete the octet of central atoms are known as elect...
Rotational barriers in 19 molecules possessing a single internal rotation angle around a B-N, C-C, C-N, C-O, N-N, N-O, O-O central bond and geometrical isomerism in 3 molecules possessing a N=N double bond have been studied ab initio by the improved bond-orbital method. The first...
It was shown that the electrostatic loop is disordered in the absence of the Cys57–Cys146 bond by small-angle X-ray scattering and H/D exchange reactions detected by NMR39. Our group also reported that, using UV resonance Raman spectroscopy, the acquisition of the pro-oxidant activity ...
The energy calculations as a function of the torsion angle () around the N(amide)–C(benzene) bond for HMepma reveal that the minimum energy synand antiperiplanar conformations of the carboxamide functions are more stable than the corresponding synand antiplanar ones (= 0 and 180°) by 0.18...
