The resolution is sufficiently high to clearly reveal the Davydov splitting of the vibronic bands. The photoexcitation spectrum of a single crystal 4 mm long shows more than 15 vibronic bands with a signal to noise ratio of the strongest band (the 0.0) of about 40 to 1. This is to be compared to the direct absorption of a crystal 40 mm long which only reveals 5 vibronic bands with a signal-to-noise ratio of approximately 4 to 1 for the $0,0$. en_US dc.format.extent 105499 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title HIGH RESOLUTION SINGLET-TRIPLET ABSORPTION SPECTRA OBTAINED BY PHOTOEXCITATION TECHNIQUES. en_US dc.type article en_US
