英文摘要 | In order to understand the nature of the driving force for distorting the non-planar molecule benzylideneaniline (NBA) away from its planar geometry, two energy effects, the vertical resonance energy Delta E-v(theta) and the sigma-pi orbital interaction energy Delta E-sigma pi(theta), were calculated with the DFT method, and then partitioned into their pi and sigma parts, denoted as Delta Ev(-pi)(theta) and Delta EV-sigma(theta), Delta E(sigma pi)-pi(theta) and Delta E(sigma pi)-sigma(theta) respectively. Delta E-V(theta) is always destabilizing, and has a tendency to distort NBA molecule away from its planar geometry as far as possible. Similarly, Delta E-sigma pi(theta) is also destabilizing, however, it is most destabilizing at the theta=90 degrees geometry. NBA molecule would prefer the theta=90 degrees geometry if there were no interaction between the a and pi systems. The fact dE(T)(theta)/d theta=0 (total energy) around theta=40 degrees geometry, is a compromise between the various orbital interactions including pi-pi, sigma-pi interactions. |
