We report correlation function quantum Monte Carlo (CFQMC) calculations of
the vibrational levels on the silanone potential energy surface developed b
y Koput and co-workers. We computed the vibrational modes up to 3500 cm(-1)
and up to the fifth excited vibrational mode. Our results are in agreement
with those reported by Koput et al. These results are important to future
theoretical and experimental investigation of the H2SiO molecule, as spectr
oscopic data in this system are scarce. (C) 2000 Elsevier Science B.V. All
