在同步加速器的辐射下，我们测量了10K时固相中几种小分子的光谱，包括纯的- o -2、NO、CO2、N2O、H2O和NH3 -，或分散在Ar中的NH3，摩尔比为1/250，从紫外区吸收开始直到晶体LiF或固体at的透射极限。在光谱数据的定量处理中，我们将总吸收剖面除以波数拟合到最小数高斯曲线上，并通过与气态光谱的比较，初步确定了电子跃迁和振动结构。这些结果阐明了固相样品在真空紫外区电子光谱的性质。(C) 2008 Elsevier B.V.版权所有
With radiation from a synchrotron we measured the spectra of several small molecular species in the, solid phase at 10K, either pure -O-2, NO, CO2, N2O, H2O and NH3 - or, for NH3 also dispersed in Ar at, molar ratio 1/250, from the onset of absorption in the ultraviolet region until the limits of transmission by crystalline LiF or solid At. In a quantitative treatment of spectral data, we fitted the total absorption profile divided by wavenumber to Gaussian curves of minimal number, and made tentative assignments of electronic transitions and vibrational structure by comparison with spectra of gaseous species. These results illuminate the nature of electronic spectra of samples in solid phases in the vacuum ultraviolet region. (C) 2008 Elsevier B.V. All rights reserved.
