for 8O1(s), which means that its intensity is lower than that of the three
frequencies actually listed.
17.8.1.2 Electronic Spectra and Rotational Data
UV-vis absorption spectra have been determined for 8O1(s). Because
Eastmond et al. [102] have measured the spectra for C

H
2
we will report
these data only and not the results for the triethylsylidyne-endcapped
derivative. Observed values of

Rotational data are reported in Reference 69.

presents their relative energies, zero point vibrational energies
and dipole moments.
17.8.2.1 Vibrational Data, Electronic Spectra, and
Rotational Data
The three strongest vibrational frequencies are presented in
Table 17.39
.
UV-vis absorption spectra have been determined for 10O1(s), including
spectra for triethylsylidyne-endcapped derivatives. Observed values of
l

Table 17.40
.
No rotational data were found.
