40. The dependence of the distribution of width on the minimal approach distance between chromophore and TLS has also been addressed in Refs. 38 and 41.

42. -r̂3 gives the probability that the closest particle of a three-dimensional, homogeneous distribution is at a distance r̂. As the frequency shift is proportional to the inverse cube of the distance, the weighted contribution of the closest TLS∼1/r̂ diverges for r̂↓0. The divergence holds for three dimensions or less.

44. For the specific system under consideration, the density of active TLS, which are not frozen during the measurement, is about 10% less than the density value used in Ref. 17. The density of active TLS may not be confused with the average density of thermally populated TLS, which is about an order of magnitude smaller for the specific case.

47. Examples for line splitting can be found in Refs. 38 and 48. These experiments were done with the same chromophore (Tr), but embedded in different hosts (polyethylene and n-alkanes, respectively). In the latter, jumping lines were purposely excluded from the distributions of linewidths.

49. For a test of the quality of this approximation, it would be useful to have the distribution of the variance from the experimental data as well.
