Figure 2. a) Comparison of spectra of Tet+ in the range of the first two electronically excited transitions obtained using the He-tagging method (bottom) and the matrix isolation technique (top, data adapted from Ref. [Citation38] and shifted to the blue by 845 cm–1). b) The spectrum of Tet+ in wavenumbers scaled relative to the 000 origin band at 859.5 nm.

Table 1. The parameters of the most intense absorption bands of Tet+Hen obtained from depletion (D) and gain (G) spectra and the prediction for Tet+. The FWHM and λmax are given in nanometres. The wavelengths are estimated for air. The relative integrated intensities of the bands (η) are calculated relative to the intensity of the 000 origin band.
