We report on the characterization of dibenzo[cde,opq]rubicene (C(30)H(14)). The molecule was studied in solution at room temperature with absorption spectroscopy in the visible (vis) and ultraviolet (UV) wavelength ranges, and with emission spectroscopy. The infrared (IR), visible, ultraviolet, and vacuum ultraviolet (VUV) absorption spectra of a thin film were measured also at room temperature. In addition, the UV/vis absorption spectrum was measured at cryogenic temperatures using the matrix isolation spectroscopy technique. The interpretation of spectra was supported by theoretical calculations based on semiempirical and ab initio models, as well as on density functional theory. Finally, the results of the laboratory study were compared with interstellar spectra.
我们报告了二苯并[cde,opq]苉（C(30)H(14)）的特性研究。在室温下，我们通过可见（vis）和紫外（UV）波长范围内的吸收光谱以及发射光谱对该分子进行了研究。还在室温下测量了薄膜的红外（IR）、可见、紫外和真空紫外（VUV）吸收光谱。此外，使用基质隔离光谱技术在低温下测量了紫外/可见吸收光谱。光谱的解释得到了基于半经验和从头算模型以及密度泛函理论的理论计算的支持。最后，将实验室研究的结果与星际光谱进行了比较。
