''An atteJDpt has been made to cOll1PlJte the numbers of certain
JI10lecules in interstellar space , . . . . A search for the bands
of CH, O/{, DR, en and C2 would appear to be proIDising" P Swings
and L Rosenfeld Astrophysical Journal 86,483(1937) This may have
been the first attempt at modelling interstellar chemistry. As with
models today, the methods used lacked reliability, but the
speculation was impressive! Mark Twain might well have said of this
infant subject "One gets such wholesale returns of conjecture out
of such a trifling investment of fact". The detection of
unidentified lines around the period that Swings and Rosenfeld were
writing provoked much interest, but even the most optimistic
speculator could hardly have imagined developments which would
occur during the next 50 years. By 1987 about 70 varieties of
molecule had been identified in the interstellar and circumstellar
regions, They range in complexity from simple diatomics such as H2
and CO to such species as ethanol C2HeDH, acetone (CHs)2CO, and the
largest interstellar molecule detected so far, cyano-penta
acetylene HC11N, The study of these molecules in astronomy has
developed enormously, especially over the last 20 years, and is now
codified in the new subject of astrochemistry, That such a variety
of chemical species should exist in tenuous regions of the Galaxy
is fascinating.
