    Las líneas espectrales no son infinitesimalmente estrechas; tienen un ancho finito. Un gráfico de radiancia o intensidad por unidad de longitud de onda (o frecuencia) versus longitud de onda (o frecuencia) es el perfil de línea. Existen varias causas de ensanchamiento de líneas, algunas internas al átomo, otras externas, y cada una produce su perfil característico. Algunos tipos de perfil, por ejemplo, tienen un núcleo ancho y alas pequeñas; otros tienen un núcleo estrecho y alas extensas y anchas. El análisis de la forma exacta de un perfil de línea puede darnos información sobre las condiciones físicas, como la temperatura y la presión, en una atmósfera estelar.
