Summary : Bond length of HCl gas



Dear CClLers
 There was a request for a summary, so here goes....
 Thank you again.
 Best wishes

 1.Please read the article in J. Chemical Physics, 109, 973-977(1998).
 >From Masao Masamura
 2.Any textbook in physical chemistry would do.
 Here it is: 1.2745 A, from Atkins, 6th edition.
 >From Jan Dillen
 3.r(e) = 1.2746 Å
 Herzberg, G. "Molecular Spectra and Molecular Structure", 2nd. Ed.,
 van
 Nostrand, Princeton (1950)
 >From Ole Swang
 4.There is a nice demo about the Morse potential to be found at
 http://www.monmouth.edu/~tzielins/mathcad/tjz/doc009.htm
 where HCl is taken as an example.
 The bond length is reported there with 1.275 * 10^-8 cm
 referring to some text book
 Physical Chemistry 3rd edition by J.Noggle p.768
 >From Siegfried Hoefinger
 5.You could try:
 http://webbook.nist.gov/chemistry
 The value from there is 1.27455 A for the electronic ground state. You can
 get the reference for this number from the web page.
 >From Gert von Helden
 6.Handbook of Chemistry and Physics
 RH-Cl=1.27246 A
 >From olivier Maresca
 7.The value of 1.27455 Angstrom can be found for the ground state in:
 Huber, Herzberg, 'Molecular Spectra and Molecular Structure 4, Constants
 of Diatomic Molecules', Van Nostrand N.Y. (1979)
 (i.e. spectroscopic data)
 >From Harald Svedung
 8.Bond length of HCl in the gas phase
 T. van Mourik and T.H. Dunning, Jr., Int. J. Quantum Chem. 76, 205 (2000).
 In this paper, we report spectroscopic constants (including equilibrium
 bond lengths, harmonic frequencies, and anharmonicity constants) of
 a few diatomic molecules, among them HCl. These have been calculated
 with several theoretical methods and the correlation consistent basis sets up to
 aug-cc-pV6Z.
