In the present article, polymethine and annulene electronic spectra are described in a unique way by means of the Pariser-Parr-Pople method. The analytical expressions were derived for the first r-electron transitions energies. The character of the annulene spectra, like the character of the open-ch
## Abstract VE‐PPP, CNDO/2, and CNDO/s‐CI methods have been used to investigate the electronic spectrum and structure of benzaldehyde. Electronic charge distributions and bond orders in the ground and lowest excited singlet π\* ← π and π\* ← __n__ states of the molecule have been studied. The molec
