Several new techniques are currently being developed for probing isolated molecules at low temperatures, allowing the detailed properties of these molecules to be characterized with minimal environmental disturbance. In this Perspective, Scoles concentrates on nanomatrix spectroscopy, a particularly powerful new tool in which inert gas clusters or droplets are used to isolate and characterize molecules and complexes not accessible by other techniques. Three recent papers by Nauta and Miller and a paper by Weber use this technique to shed light on solvation and structural metastability.
