HCO+
(ionized compound of hydrogen, carbon, and oxygen, one atom each)
HCO+, i.e., an ionized molecule of
hydrogen, carbon, and oxygen, is used as a tracer
of certain characteristics of interstellar medium clouds.
Its rotational spectral lines are detectable in the
millimeter range viewable by ALMA.
| HCO+(1-0) | 89.1885 GHz | 3.36mm |
| HCO+(3-2) | 267.5576 GHz | 1.12mm |
It has the advantage of being more sensitive to some
conditions than other common tracers.
Neutral HCO is also of astrophysical interest,
as are DCO+ and H13CO+.
