Accessible solvent channels and the presence of weak and reversible non-covalent C-H … π, π … π,C-H…X, and X…X interactions account for the vapoluminescent behavior of 4a. The sensitivity of the emission properties of squar planar Pt(II) complexes is the basic operating principle behind their application as molecular VOC sensory materials. Excimers ~~ excited-state dimers excimeric (A-A*) 3ππ* Vibronic Coupling When there is an atom common to the two vibrations. Bending vibrations requires a common bond between the vibrating groups. The stretching bond forms one side of the angle that varies in the bending vibration. The coupled groups have individu
