Therefore, at extremely low temperatures one may equally choose between TLS and say oscillator bath. The latter is usually supposed to be simpler to handle, but the TLS bath model, apart from its apparent relevance for glass theory, has some very attractive features [Mermin 1991 Suarez and Silbey 1991b Shimshoni and Cefen 1991]. 

There is a vast field in chemistry where the spin-boson model can serve practical purposes, namely, the exchange reactions of proton transfer in condensed media [Borgis et al. 1989 Suarez and Silbey 1991a Borgis and Hynes 1991 Morillo et al. 1989 Morillo and Cukier 1990]. 

Borgis et al. 1989 Suarez and Silbey 1991a], where q is a particular coupling coordinate from the set qj which modulates the barrier (we assume for simplicity that there is only one such coordinate), and the exponential form of A is accounted for by the Gamov-factor nature of this term. 

The analytic results for the spin-boson Hamiltonian with fluctuating tunneling matrix element (5.67) are investigated in detail by Suarez and Silbey [1991a]. Here we discuss only the situation when the qi vibration is quantum, i.e., (o P P 1. When the bath is classical, cojP, j 1, the rate... 

The Suarez modification of the Hofmann-Loffler-Freytag reaction was review by... 

In conclusion, the Hofmann-Loffler-Freytag reaction tends to give moderate and sometimes poor yields for the preparation pyrrolidines under the classic conditions. Nonetheless, the utility of this reaction to functionalize molecules via the aminyl radical mechanism plays an unique role in the tool box for the organic chemist, enabling transformations not easily achievable using other means. Furthermore, milder conditions and better yields can be achieved by taking advantages of the newer developments such as the Suarez modification.
