Summary
The spectrum of AlH+ at 3632 Å has been observed in emission using an aluminium arc at low pressure in an atmosphere of hydrogen. The photographs were taken in the third order of a 3.4 m Ebert spectrograph having reciprocal dispersion of 1.5 Å/mm. The spectrum obtained is a typical2 Π-2 Σ transition consisting of (0, 0) and (1, 1) bands. Rotational analysis has been performed and the constants have been evaluated.
Riassunto
Si è osservato lo spettro di AlH+ a 3632 Å in emissione per mezzo di un arco ad alluminio a bassa pressione in un’atmosfera d’idrogeno. Le fotografie sono state fatte al terzo ordine di uno spettrografo di Ebert di 3.4 metri con dispersione reciproca di 1.5 Å/mm. Lo spettro ottenuto è una tipica transizione2 Π-2 Σ composta dalle bande (0, 1) e (1, 1). Si è effettuata l’analisi rotazionale e si sono calcolate le costanti.
Реэюме
Наблюдается спектр иэлучения AlN+ при 3632 А, испольэуя алюминиевую дугу при ниэком давлении в атмосфере водорода. Фотографии сделаны в третьем порядке на 3.4-метровом спектрометре Эберта, имеюшем обратную дисперсию 1.5 Å/мм. Полученный спектр представляет типичный2 П-2Σ переход, содержаший (0,0) и (1,1) эоны. Проводится ротационный аналиэ и оцениваются постоянные.
