Abstract | The absorption spectrum of CIF in the region 1400-1290 Å has been photographed at a dispersion of 0.18 Å/mm. The spectrum consists of bands degraded to shorter wavelengths and arises from transitions to the four components c3Π2, c3Π1, c3Π0, and C1Π1 of the first s Rydberg complex built on the X2Πi core of CIF+. Strong spin-orbit interactions distort the spin splitting of the triplet state and produce an unusual intensity distribution in the weak c3Π0 ← X1Σ+ transition. Upper state vibrational and rotational constants are given for the more abundant isotope 35CIF. |
