Study of the satellite bands of RbCs molecule in the near UV

摘要

By comparing high-resolution absorption spectra of Rb and Cs vapor with Rb-Cs vapor mixture spectrum we were able to identify several satellite bands of RbCs molecule at 362.2 nm, 372.5 nm and 390.7 nm. These bands represent lower Rydberg states of the RbCs molecule which may be further studied at ultracold conditions.
