  We present our recent spectrophotometric results of the infrared luminous
Seyfert 2 galaxy NGC 7679. We find compelling evidence of the presence of a
recent nuclear starburst, revealed by the observations of a) the spectral
features of high order Balmer absorption lines, b) the weak equivalent widths
for CaIIK $\lambda$3933, CN $\lambda$4200, G-band $\lambda$4300 and MgIb
$\lambda$5173, and c) the suggested UV stellar wind resonance lines (N V
$\lambda$1240, Si IV $\lambda$1400 and C IV $\lambda$1550) in the IUE spectrum.
Using the simple stellar population synthesis model, we find that in the
nuclear 2" $\times$ 2" region, the contributions from the old, intermediate and
young components are 21.7%, 42.9% and 35.4%, respectively. These nuclear
starburst activities might be triggered by the close encounter with NGC 7682,
as suggested by recent numerical simulations.
