An emission spectrum of hot water with a temperature of about 3000 K is obtained using an oxy-acetylene torch. This spectrum contains a very large number of transitions. The spectrum, along with previous cooler laboratory emission spectra and an absorption spectrum recorded from a sunspot, is analyzed in the 500-2000 cm(-1) region. Use of a calculated variational linelist for water allows significant progress to be made on assigning transitions involving highly excited vibrational and rotational states. In particular emission from rotationally excited states up to J=42 and vibrational levels with up to eight quanta of bending motion are assigned.
使用氧乙炔炬获得了温度约为3000 K的热水的发射光谱。该光谱包含大量跃迁。在500 - 2000 cm(-1)区域对该光谱以及先前较冷的实验室发射光谱和从太阳黑子记录的吸收光谱进行了分析。使用计算得到的水的变分谱线表，在确定涉及高激发振动态和转动态的跃迁方面取得了显著进展。特别是确定了高达J = 42的转动激发态和具有多达八个弯曲运动量子的振动态的发射。
