The UV spectra of N,N′-phenylcyclodisilazanes, N-trimethylsilylaniline and N,N-bistrimethylsilylaniline have been investigated with the aid of UV and quantum mechanical calculations. The main difference between the spectra of N,N′-phenylcyclodisilazanes and that to aniline-like molecules is a strong bathochromic shift of 20-30 nm of the p-bands. This is explained in terms of significant through-space interaction between the N atoms and conjugation of in-plane phenyl groups.
