Scientific paper

Dusty models of the infrared line emission from G45.5+0.1 (No. 2), W3 A/IRS 1, S88 B, and G29.9-0.0 are presented. These models match the observed radio and near-infrared continua from the H II regions. For those nebulae that have been observed with infrared spectrometers, the predicted intensities fall at least a factor of 10 below the observed ones. This difference is attributed to lack of knowledge of interstellar dust's optical properties in the ultraviolet and/or the validity of stellar atmosphere models in the ultraviolet.
