The conformational flexibility in the polypeptide chain is conferred by rotation about the bonds on either side of the α-carbon atom; these bond angles are referred to as phi and psi angles. The angle of the N–Cα bond is the phi angle (Φ), and that of the Cα–CO bond is the ...
Another feature of HB which adds to the complexity of its description is directionality; frequently, the angle A–H⋯B is not straight, meaning that the interaction is not purely electrostatic, and that a partial degree of covalency exists. This effect can be understood in terms of partial ...
A series of excited electronic states of AH2 molecules having extremely small bond angles has been discovered theoretically. Systems which have shown this characteristic to date include H2O+, NH2, CH2+, and NH2+. In the present research ab initio studies were carried out using a double zeta ...
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...
