| | The UMIST Rate99 Database for Astrochemistry (Site not responding. Last check: 2007-10-08) |
 | | The latest version of the UMIST database, RATE99, provides the rate coefficients of 4113 gas-phase reactions among 396 species involving the 12 elements H, He, C, N, O, Na, Mg, Si, P, S, Cl and Fe. |
 | | With the exception of the elements Na, Mg and Fe, which are included in the ratefile to produce a source of ionisation in dark clouds, the chemistries of the other elements are fairly comprehensive. |
 | | Astrophysics at UMIST and the work of YHLT in particular are supported via a grant from the Particle Physics and Astronomy Research Council (PPARC). |
