Weboctatetraene (a) and monocis octatetraene (b) in hexane. The ex-tinction coefficients are not known; so the spectra have been scaled to equal heights. The absorbance bands from 310 to 250 nm corre-spond to the l1Ag -* llBu transition of a linear polyene of C2h sym-metry. The all-trans origin is at 302 nm and the monocis origin is at 301 nm.
