【摘要】 建立了气体OARS实验装置,并进行了硝基苯蒸气CARS谱的初步研究。发现硝基苯的—NO₂对称伸缩振动模(=1345厘米^-1)在相变时有频率位移,气相谱线较液相的明显展宽,并呈现不对称性。更多还原

【Abstract】 An experimental set-up for CARS investigation of gas systems has been established and CABS spectrum of nitrobenzene vapor has been measured. In comparison with the CARS spectrum of liquid phase nitrobenzene, a frequency shift of the NO2-symmetric stretching mode(v =1345cm-1) was observed for the vapor phase. Besides, the CARS spectrum line of nitrobenzene vapor was found to be asymmetric and much broader than that of liquid nitrobenzene.更多还原
