记录和分析了PtF在15,252 cm−处发生的电子跃迁的转动分析。这种转变被认为是[15.3]Ω=3/2-X2Π3/2电子转变的(0，0)带。PTF分子是在电流调节的射频脉冲直流放电中产生的，工作电流为0.80A，在0.50-1.25Torr的1-5%SF6的Ar/He混合溅射气体中作用于铂衬里的铜空心阴极。将空心阴极置于14,500-16,500 mm−可调谐染料激光器的谐振腔内，采用腔内激光光谱(ILS)方法，利用0.2-2.0 mm的光程。数据用多项式能级表达式在PGOPHER中进行了拟合。给出了激发态的分子常数。讨论了新的[15.3]Ω=3/2态的性质。
A rotational analysis of the electronic transition of PtF occurring at 15,252 cm−1was recorded and analyzed. This transition is identified as the (0,0) band of the [15.3]Ω=3/2 –X2Π3/2electronic transition. The PtF molecules were produced in a current regulated RF-pulsed DC discharge operating with 0.80 A applied to a Pt-lined copper hollow cathode in 0.50–1.25 Torr of 1–5% SF6in an Ar/He sputter gas mixture. The hollow cathode was placed within in the resonator cavity of a tunable DCM dye laser operating over the 14,500–16,500 cm−1range, and path lengths of 0.2–2.0 km were utilized with the intracavity laser spectroscopy (ILS) method. The data were fit in PGOPHER using a polynomial energy level expression. Molecular constants for the excited state are presented. The nature of the new [15.3]Ω = 3/2 state is discussed.
