摘要：
The infrared absorption spectrum of SF6 embedded in large liquid He-N clusters was studied in the range around 946.3 cm(-1) using a cw diode laser. A sharp peak (fwhm < 300 MHz) accompanied by two weaker satellite bands of larger halfwidth (approximate to 1 GHz) were recorded for different mean He cluster sizes (<N-0>=1000-5000). The satellite bands are size dependent and can be fit by assuming that the SF6 molecules with several rigidly attached He atoms rotate freely within the He cluster. Phonon satellites involving several different types of possible vibrations are also considered as a possible explanation.
