(all versions) Color error corrected in the Stark-shift plot.
(Rubidium 85) Minor formatting error corrected in Table 13 (thanks to James Bateman for pointing this out).

30 April 2008

New versions: Cs (2.0), Na (2.0), Rb 87 (2.0), Rb 85 (0.1, new document!).
(all versions) Changes under the hood: all data in the document are now automatically generated and inserted into the document by various scripts, hopefully reducing transcription errors by the author.
(Cs data) References to numerical hyperfine constant values in the text now include factors of h for consistency of units. Thanks to Marlon Nakat for comments leading to this correction.
(all versions) Fundamental constants updated to 2006 CODATA recommended values. Thanks to Greg Smith for bringing this to my attention.
(all versions) Updated conversion factor for polarizability in text.
(all versions) Revised Edlen formula and indices of refraction for computed air wavelengths (thanks to Windell Oskay for appropriate references).
(all versions) Improved formulae for weighted averages implemented that better account for inconsistencies of measurements. Some uncertainties listed have increased as a result.
(Na version) Changed ground-state polarizability to SI value listed in Ref. [40] (previously listed value was converted from the cgs value in the same reference). Thanks to Erik Streed for pointing this out.
(Na version) Slight change to D1 vacuum wavelength value (about 2 ppm) and associated derived values. Thanks to Horst Knoeckel for pointing out that I had transcribed the wrong value from Ref. [6].
(Na version) Transcription error fixed for effective cross section for isotropic light (in the exponent) in Table 7. Thanks to Michael Johanning for pointing this out.
(all versions) Fixed Eq. (61): the dipole matrix element on the left-hand side should have been squared. Thanks to Paul Hillman for pointing this out.
(all versions) Minor change (less space) to typesetting style in punctuation in equations.
(Rb versions) Added isotope shifts.
(all versions) Many new measurements added, and I hope not as many new errors.
(all versions) All hyperfine diagrams have level intervals visually shown in correct proportion (within each manifold, anyway).

14 October 2003

New versions: Cs (1.6), Na (1.6), Rb 87 (1.6).
(Rb 87 data) Fixed D2 line transition frequency error. Thanks to Mark Saffman for pointing this out.
(Rb 87 data) Fixed energy level notation in Table 6 (electric/magnetic field properties). Thanks to Blair Blakie for pointing this out.
(All versions) Fixed dipole-moment relation in discussion of optical pumping from linearly polarized light (currently Section 4.3.2), also Eq. (63), and the numerical value of the saturation intensity in this same section. Thanks to Markus Kottke for this correction.
(All versions) Fixed Eq. (54) defining the magnetic-sublevel Rabi frequencies W(m_e, m_g), and deleted superfluous minus signs in the following discussion of W_q. Thanks to Markus Kottke for comments leading to this correction.
(All versions) Added center transition energies in eV.
(All versions) Added note about Clebsch-Gordan coefficient phase convention and reference to formulae. Thanks to Björn Brezger for this suggestion.

A tricyclic antidepressant with a relatively short latency period. It has almost no sedative effect. therapeutical indications include: depressive phases of a manic-depressive psychosis, all other forms of endogenous depression (reactive and neurotic). In combination with amitriptyline it is used for depressions that occurred during treatment with reserpine. In combination with neuroleptics, it is used in the treatment of depression that develo
