  The B36N36 fullerene-like cage structure was proposed as candidate structure
for the single-shell boron-nitride cages observed in electron-beam irradiation
experiment. We have performed all electron density functional calculations,
with large polarized Gaussian basis sets, on the B36N36 cage. We show that the
cage is energetically and vibrationally stable. The infra-red, Raman and
optical spectra are calculated. The predicted spectra, in combination with
experimentally measured spectra, will be useful in conclusive assignment of the
proposed B36N36 cage. The vertical and adiabatic ionization potentials as well
as static dipole polarizability are also reported.
