Abstract
The observation of triplet–triplet absorption and emission spectra of salicylidene- m-bromo-aniline in solution, is complicated by the possible colored isomer formation during the optical pumping for yotta-photonic excitation at room temperature. The short-lived (singlet–singlet) and long-lived (triplet–triplet) absorption spectra were recorded phographically by microsecond flash and nano-second laser flash photolysis techniques. Salicylidene- m-bromo-aniline complexes were purified by repeated recrystallization until further recrystallization produced no further changes for X-ray diffraction pattern and optical absorption, emission properties. For yotta-photon excitation system, light could be faster than usual, because of heat and to many photonic collisions in the cavity, slowed down by the molecule, and stopped or frozen in a molecular orbital for a short time from nano-second to atto-second. The physical properties of the absorbed photons, in a very high photon flux density (i.e. in a photon field) are different in photonic character, and the emitted photons by the excited states behaves differently in photon field, no splitting occurs for the absorbed or emitted lines like in electrical or magnetic fields.
