Scientific paper

The paper reports measurements of the absolute and relative line intensities obtained in five different positions in the inner 20 arc sec of the peculiar spiral galaxy NGC 3310. The H II regions are two to six times more luminous than an average giant H II region, of unusually low metal abundance, and may exhibit a very high nitrogen to oxygen abundance ratio. An east-west vs. north-south asymmetry apparent in the optical and radio continuum is also reflected in the characteristic excitation of these H II regions.
