【摘要】 建立了用傅立叶变换红外光谱和中红外差频激光光谱方法研究氢基质隔离光谱的测量装置.作为装置的测试,观测了3cm长的固态氢分子晶体在1-5μm波段的吸收光谱.并用中红外差频激光测量其在2410cm-1附近的W0(0)(v=0←0,J=6←0)谱线的高分辨精细结构.通过在低温基片上喷溅沉积氢分子晶体薄膜的方法,对氢基质隔离的CO2分子的高分辨红外吸收光谱进行了研究.更多还原

【Abstract】 Apparatus integrating a Fourier transform-infrared (FT-IR) spectrometer and a mid-infrared difference frequency generation (DFG) laser spectrometer was built for the study of the matrix isolation spectrum in solid molecular hydrogen. A 3-cm-long molecular hydrogen crystal was grown in a liquid-helium Dewar and its infrared absorption spectrum in the 1-5 μm region was recorded to test the system. The W0(0) (v=0←0, J=6←0) line around 2410 cm-1 of solid hydrogen was investigated with the DFG laser spectroscopy. High-resolution matrix isolation spectrum of CO2 co-deposited with hydrogen on a BaF2 cold plate at liquid-helium temperature was studied.更多还原
