Abstract:
We report on the IR-spectra of HDO and aggregates of HDO and N(2) embedded in superfluid helium nanodroplets in the region of the bound O-D stretch vibration. The R(0) transition 0(00)→1(01) of HDO was observed at 2738.157 50(7)cm(-1). The linewidth of this transition was determined to be 0.060(4)cm(-1). In HDO(N(2))(n) aggregates, the bound O-D stretch vibration was observed at 2732.36(1) and 2730.62(1)cm(-1) for n=1 and n=2, respectively. The line broadening amounts to 1.86(7) and 2.73(7)cm(-1), which correspond to lifetimes of 2.84(1) and 1.94(5) ps.
