Abstract
In experiments with a single molecule we deal with a guest molecule doping a polymer or a glassy solid matrix cooled down to 4.2 K and even less. Despite such cooling of the solid and guest molecule, we cannot remove the interaction of the molecule with phonons and tunnelons, because creation of phonons and tunnelons during optical excitation is possible even at T = 0. Such a single molecule interacting with low frequency excitations in a solid is called an impurity center.
