## Abstract This paper reports a systematic PCILO study of the conformation of the nucleic acid backbone. The authors principally studied the ω′ and ω phosphodiester torsion angles of the disugar triphosphate model as a simultaneous function of (1) the sugar nature, ribose or deoxyribose, (2) the d
Coupling constants of 35 substituted pyridines are discussed and related to the electronic properties of the substituents and to the mechanism of coupling. A calculation of J i s performed using Pople and Santry's theory and mutual polarizabilities obtained by CND0/2 or Hoffmann methods. The influen
