Normal red giants of a given spectral type are shown to be heterogeneous with respect to the following chromospheric features: the Balmer absorption lines, the emission line at H∊, and the double-reversed emission lines at Caii H and K. These chromospheric lines are also shown to be strongly time variable, in at least some red giants, on a time scale of a few months or years. Other chromospheric features that require study lie in the infrared (Hei 10830), the near ultraviolet (Feii emission lines), and the vacuum ultraviolet.

Asymmetric Top

The red absorption bands of CH 2 , previously shown to correspond to a transition between singlet states, have been analysed in detail. In the lower electronic state a 1 A 1 the molecule is a strongly asymmetric top with rotational constants A 000 = 20.14, B 000 = 11.16 and C 000 = 7.06 cm -1 . From these constants a CH distance of 1.11 A and an HCH angle of 102.4° is obtained. In the upper state b 1 B 1 the molecule is nearly linear, having an HCH angle of about 140° and a CH distance of 1.05 A. Most of the observed absorption bands correspond to excitation of the bending vibration v 2 in the upper state (v 2 = 6, 8, ..., 18). In some of them in addition the symmetric stretching vibration v 2 is singly excited. The levels 1, v 2 -4, 0 cause strong perturbations in the levels 0, v 2 , 0 for v 2 = 8, 10, 12, 14. In the lower state only one excited vibrational level 0, 1, 0 has been established which yields v 2 = 1352.6 cm -1. Fragments of some other singlet absorptions in the near ultraviolet and in the vacuum ultraviolet have been observed and are briefly described. The upper state of the near ultraviolet system is probably the predicted 1 A 1 state corresponding to 1 E + in the linear conformation.

AbstractThe principles and the realization of an experiment devoted to oscillator strength measurements in the vacuum-ultraviolet by the emission method are briefly presented. The results obtained for the strong multiplets of neutral nitrogen and carbon in the 1200-2000 Å range yield an absolute scale of oscillator strengths in good agreement with the most recent calculations.
