在高压下测量了取向并四苯和并五苯薄膜的吸收光谱。取向膜中0-0带的Davydov分裂随着压力的增加而增加，并四苯的分裂率为37 cm−1/kbar，并五苯的分裂率为70 cm−1/kbar。两种取向膜的0-2电子振动带都比0-1电子振动带有较大的红移。对于非晶薄膜，在大气压下没有观察到Davydov分裂。非晶态的压力诱导光谱红移略大于晶态。
Abstract The absorption spectra of oriented and amorphous naphthacene and pentacene film have been measured at high pressure. The Davydov splitting of 0–0 band in oriented films increase with increasing pressure at the rate of 37 cm−1/kbar for naphthacene and 70 cm−1/kbar for pentacene. The 0–2 vibronic bands of both oriented films show the large red shifts compared with the 0–1 vibronic band. For amorphous films the Davydov splitting is not observed at atmospheric pressure. The pressure induced spectral red shifts in the amorphous state are slightly larger than those in the crystalline-state.
