摘要
The quantum chemical calculations at the different levels of theory were performed with the target being to determine the vibration frequencies and to estimate the barriers to internal rotations of n-pentane molecules. In connection with the observed losses of CH, and CH, from the n-pentane in gas phase, the calculations at the B3LYP level of theory with the 6-31G(d) basis set were used to study the ground-state potential energy Surface of the n-pentane.
