Dispersion can be achieved by refraction, diffraction or interference — that is, by prisms, gratings or interferometers. This distinction is in a way rather artificial, because all these instruments work by superposing a number of rays of varying p

Any observed spectral line shape is a convolution of the true (source) line profile with the instrument function (Chapters 5–7) or the laser bandwidth (Chapter 8). Accurate measurements of wavelengths and intensities, as well as sensible choices of

Microwave and radiofrequency spectroscopy measure directly relatively small energy separations, between about 10 cm-1 and a few thousandths cm-1, or 300 GHz to 30 MHz. The short wavelength end of this range (1 mm < λ < 10 cm, say) comprises pure rot

The preceding chapters have shown that the widths, shapes and intensities of spectral lines depend on the temperature, pressure and electron density of the environment of the atom or molecule, as well as on its intrinsic properties. If the broadening

Reliable values for transition probabilities are widely required, particularly in astrophysics and laboratory plasma physics. Most such values are obtained experimentally; calculations tend to be of doubtful reliability unless they have been experime

Light sources for spectroscopy may be divided into broad-band (or continuum) sources suitable for intensity standards or as backgrounds for absorption spectroscopy, and narrow-band (or line) sources for emission spectroscopy.Consideration of lasers i
