It is well known that vampires have a number of super-human powers (Melton 1994), although not all sources agree on the exact nature of these powers. This disagreement is presumably due, in large part, to a lack of careful scientific study of these creatures. According to early experts, one of the more interesting abilities of vampires is that they can turn into a mist/gas/vapor at will and move about in this gaseous state (Stoker 1897; Dean, Balderston et al. 1931; de Sangre 1952; Wallace et al. 1967). In the paper that follows we discuss a number of questions associated with the nature of vampires in the gaseous state, hereafter referred to as vampire(g),1 and attempt to estimate some of the chemical and physical properties of vampires while in this state. While we make some progress in this regard, it is difficult to constrain many important properties of gas phase vampires on the basis of current information. In these cases we provide some discussion concerning the merits and difficulties associated with analytical techniques that might yield additional pertinent information.
