Due to the important pharmaceutical activities of benzimidazole derivatives, the differences between 2-(2'-pyridyl)benzimidazole and 2-(4'-pyridyl)benzimidazole were researched by terahertz time-domain spectroscopy and density functional theory systematically. Although the only difference between their molecular configurations is the different arrangement of nitrogen on pyridine ring, 2PBI and 4PBI have large differences in their experimental absorption spectra in the range of 0.2-2.5THz, such… CONTINUE READING
