STRUCTURE OF THE BAND SPECTRUM OF THE CuI MOLECULE: II. ROTATIONAL STRUCTURE OF THE C AND D SYSTEMS OF 63Cu127I
Keyword(s):
The C and D band systems of 63Cu127I, lying in the region 4 100–4 800 Å, have been photographed in emission under high resolution. Rotational analysis of the (0–0), (0–1), and (0–2) bands of the C system and the (0–0), (0–1), (0–2), and (0–3) bands of the D system has been made. The C and D systems are found to involve 1Σ (C1Σ)–1Σ(X1Σ)and 1Π(D1Π)–1Σ(X1Σ) transitions respectively. The Λ-type splitting in the D1Π state is small. The rotational constants obtained are as follows (cm−1 units):[Formula: see text]
