Abstract: | Physical principles are considered for this method of examining interactions. Changes in absorption and fluorescence spectra are examined in relation to Van der Waals, electrostatic, and exchange interactions. Major spectral criteria are presented for the types of interaction and are illustrated by reference to naphthalene adsorbed on zeolites. Spectra at 77 K show that the adsorbed molecules are in two different states: in one they are bound by Van der Waals forces, while in the other a charge-transfer complex is formed. Examination at intervals after preparation shows that the adsorbed naphthalene is gradually oxidized. |
