| Abstract: | The electronic absorption transitions for 2,3-bis(2,4-dimethylthiophen-3-yl)maleic anhydride were calculated by (time-dependent) method with 6-31G(d) basis at structures optimized at B3LYP/6-31G(d) level. The S_1, S_2, and S_3 transitions calculated for the open and the closed forms of the compound are 390, 360.5, 339.4; 584.6, 395.8, 370.2 nm, respectively. The results are comparable to the electronic absorption spectrum of 2,3-bis(2,4,5-trimethylthiophen-3-yl)maleic anhydride which bears extra methyl groups that should not have much effects on the spectrum. The oscillator strengths are well correlated to the spectrum peak heights. |
