The relationship between the local backbone conformation and bond angles at Cα of symmetrically substituted Cα,α-dialkylated glycines (Cα,α-dimethylglycine or α-aminoisobutyric acid, Aib; Cα,α-diethylglycine, Deg; Cα,α-di- n -propylglycine, Dpg) has been investigated by molecular dy...
Direct molecular editing of heteroarene carbon–hydrogen (C–H) bonds through consecutive selective C–H functionalization has the potential to grant rapid access into diverse chemical spaces, which is a valuable but often challenging venture to achieve in medicinal chemistry1. In contrast to electronic...

Microwave Spectrum, Molecular Structure of Vinyl Cyanide and a Summary of CC, CH Bond Lengths in Simple Molecules The microwave spectra of six isotopic species of vinyl cyanide (acrylonitrile) CH2CHCN have been investigated. From the rotational constants it is shown th... CC Costain,BP Stoicheff...
This known quantum chemical utility will be applied to C(O)OC, c-C22O22, and their silicon analogues in order to give deeper insights into how these molecules may be observed and what such observations may imply for molecular astrophysics. 2. Computational Details The QFF computations involving...
Geometry optimizations were carried out using the conjugated gradient method, with the convergence criteria for the total energy and atomic forces being 1 × 10−4−4 eV and 1× 10−3−3 eV/Å, respectively. A primitive unit cell, with one transition metal and two sulfur atoms, was...
