This article describes the analysis and interpretation of rovibrational spectra involving highly excited vibrational states in the molecule of HCN. The spectra were obtained by means of the vibrationally mediated photodissociation technique. Analysis of the spectra revealed four bands with Sigma-Sigma structures that, once fitted, provided the energies and rotational constants of four new, highly excited vibrational states in the region of the potential energy surface near and above 30 000 cm(-1). All the states could be identified with the help of a state-of-the-art variational calculation. Together with the states already observed in previous works, eight highly excited states have so far been identified in this region.
本文描述了对涉及HCN分子中高激发振动态的振转光谱的分析与解读。这些光谱是通过振动介导的光解离技术获得的。光谱分析揭示了四个具有西格玛-西格玛结构的谱带，经拟合后得到了势能面在30000厘米⁻¹及以上区域内四个新的高激发振动态的能量和转动常数。借助先进的变分计算可识别所有这些态。与之前工作中已观测到的态一起，目前在该区域已识别出八个高激发态。
