Abstract

We present the recent results obtained with multi-wavelength observations of three Galactic HII regions. Our findings suggest these regions are likely candidates of triggered star formation, where star formation in their vicinity has occurred recently due to compression or heating of the molecular gas by UV radiation from the OB stars.
