Abstract:

The molecular structure of PCl3 has been studied by electron diffraction from the vapor at nozzle temperatures of 300 and 505 K. THE SIZE OF THE MOLECULE AND THE DISPLACEMENT OF THE ATOMS DURING MOLECULAR VIBRATION ARE FOUND TO BE SIG NIFICANTLY GREATER AT THE HIGHER TEMPERATURE The P-Cl and Cl...Cl distances are longer by 0.3 and 0.4, respectively, and the rms amplitudes associated with these distances are greater by a striking 19 and 31. Both are increased size of the molecule and increased amplitudes are in very good agreement with prediction from simple theory. Author
