Spectrum of BaH at 3800 Å

Спектр BaH при 3800 Å

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

A new band of BaH has been observed in absorption at 3800 Å by using a 21 ft concave-grating spectrograph. The band has been analysed to be the (0, 0)-band of a new system namedN 2Σ-X 2Σ. Strong perturbations have been observed in the upper stateN 2Σ. The following band constants have been determined. νorig=26299.5cm−1,B′=3.59cm−1,D′=3.41·10−5cm−1.

Riassunto

Si è osservata una nuova banda del BaH in assorbimento a 3800 Å usando uno spettrografo con reticolo concavo di 21 ft. La banda è stata analizzata essere la banda (0,0) di un nuovo sistema chiamatoN 2Σ-X 2Σ. Si sono osservate perturbazioni forti nello stato più altoN 2Σ. Si sono determinate le seguenti costanti di banda: νorig=26299.5cm−1,B′=3.59cm−1,D′=3.41·10−5cm−1.

Резюме

Обнаружена новая зона BaH в спектре поглощения при 3800Å, используя 21 ft спектрограф с вогнутой решеткой. Анализ обнаруженной зоны показывает, что это (0,0) зона новой системы, называемойN 2Σ-X 2Σ. В верхнем состоянииN 2Σ наблюдаются сильные возмущения. Определены следующие постоянные зоны: νorig=26299.5cm−1,B′=3.59см−1,D′=3.41·10−5см−1.
