We present spectroscopic data of 3 isolated Vega-type systems which exhibit the 3.3 μm‘PAH’ feature ascribed to stretching of the C-H bonds in aromatic hydrocarbons. These are part of a sample of mainly hot stars. We discuss the implications of Vega-type stars having an organic component to their surroundings and compare them with the unique star, HD135344 (SAO 206462).
