    "abstract": "We address the problem of spin dynamics in the presence of a thermal bath, by\nsolving exactly the appropriate quantum master equations with\ncontinued-fraction methods. The crossover region between the quantum and\nclassical domains is studied by increasing the spin value S, and the asymptote\nfor the classical absorption spectra is eventually recovered. Along with the\nrecognized relevance of the coupling strength, we show the critical role played\nby the structure of the system-environment interaction in the emergence of\nclassical phenomenology.",
