Atomic Lines

Here is an atomic line list kindly provided by Dieter Lutz (ISO SWS IDT, MPE, Garching) and Sean Colgan (NASA/ARC) which you may find useful for planning your ISO observations. Additional references and notes were provided by Mike Haas (NASA/ARC).

NOTE: This is NOT the final line database that will be used for calibration of the ISO spectrometers. That information will be made available if and when it becomes public.

WAVELENGTH NOTES:               

The NII, OI, CII, and SiI wavelengths have all been measured with Laser
Magnetic Resonance techniques and are well known:

1: The [NII] lines have recently been measured in the lab via the LMR technique
by John Brown et al. He told Rubin his preliminary frequencies are 1461.1314
and 2459.3815 GHz (estimated error 0.001) for the J = 1--> 0 and J = 2--> 1.
This gives lambda of 205.1783 and 121.8975 microns. Andrew Cooksey told Rubin
that there was a slight error in his earlier J = 2--> 1 measurement and that
he concurs with the new value.

Update on [NII] line lab frequencies: 1461131.8 +- 0.7 MHz for J = 1--> 0.
The reference is John Brown and K.M. Evenson, in preparation.  This gives
lambda of 205.1783 microns (Mike gets 205.1782). The J = 2--> 1 frequency is
still preliminary, at 2459379.5 +- 0.6 MHz, yielding lambda of 121.8976 microns.

2: The OI line - 63.1700 um:
   Saykally etal. 1979, JChemPhys, 71, 1564 Watson etal. 1984,
   ApJ, 279, L1 says its 63.18372+0.00003 and refers to Evenson, 1982,
   private communication.
   This must supercede the 63.1700 value, but am checking it out.

All these are presumably known to 0.0001 um or so. See references for details.

3: Surprisingly, the wavelengths of the doubly ionized lines are rather poorly
known. The values we are using come from Moorwood etal. 1980, ApJ, 238, 565
and are very old and not all that well determined. The CGS on the KAO (Erickson, PI) can only do slightly better, having uncertainty of 1/2 channel or more,
being respectively, 0.004, 0.008, and 0.006 microns at 52, 88, and 57 microns.
Many people use 57.317 for the wavelength of the NIII line, including the FIFI
group (R. Genzel, PI), and this may fit the CGS data better, but the CGS group
are not yet sure. We are also not sure where this number originated.
Moorwood's paper is worth looking at just to see how FIR spectroscopy has come.
