Abstract

We report on the assignment of inequivalent C–H local modes in naphthalene by observation of overtones of symmetrically deuterated naphthalene (αd_4) at low temperatures (1.3–2 K). Careful lineshape analysis gives information on the dephasing of these high-energy states as inferred from homogeneous linewidths. We observe new trends in the linewidths that suggest the relative importance of local-normal and local-local mode coupling.
