| Abstract: | We measured 785 nm excited Raman and infrared spectra of pentacene-d14. The observed spectra were assigned on the basis of the Raman and infrared spectra calculated by the density functional theory (DFT) method at the B3LYP/6⬜311 + G** level. We measured 785 nm excited Raman spectrum of a pentacne-d14:C60 bulk heterojunction film. The spectrum was assigned on the basis of the wavenumber shifts upon deuteration of pentacene. The assignments of the 1462 and 493 cm↙1 Ag bands of C60 were confirmed. The 511, 453, and 256 cm↙1 bands, which were observed only in pentacene:C60 bulk heterojunction films, did not show large deuteration shifts. This result indicates that the 511, 453, and 256 cm↙1 bands are attributed to activation of the silent modes of C60 due to symmetry lowering. |
