Dipole moment of vinyl fluoride.

Microwave spectra of vinyl fluoride and its nine isotopic species were measured in order to establish the r s structure. I was checking dipole moment orders and came across a very peculiar result. Its molecular dipole moment is 1 4 debye and heat of vaporization is 361 kj kg. The microwave spectrum and dipole moment of vinyl iodide obtained using a computer controlled spectrometer j.

Molecules with non zero dipole moment are called polar. Dt cramb mcl gerry w lewis bevan determination of rotational constants using nuclear quadrupole hyperfine structure. An example of such a molecule is water h 2 o h 2o h 2 o. Very small volume fraction 0 035 both inclusion.

The conformers are designated as gauche trans axial etc. Dipole moment this page provides a list of dipole moment for about 800 molecules including organic and inorganic. In some cases an average value obtained from measurements on the bulk gas is. Dipole moments of individual conformers rotational isomers are given when they have been measured.

The dipole moment of the normal species of vinyl fluoride is μ a 1 284 0 004 μ b sub 0 712 0 012 and μ sub total sub 1 468 0 007 d. Its critical point is at 54 8 c 328 k and 5 24 mpa. Vinyl fluoride is classified as an iarc group 2a carcinogen likely to cause cancer in humans. Atoms such as chlorine ci and vinyl fluoride vf.

The fluoride concentrations in the urine of rats were found to be increased 45 and 90 days after exposure by inhalation to 0 200 2000 or 20 000 ppm 373 3733 or 37 333 mg cu m vinyl fluoride for 6 hr per day five days per week for about 90 days. Fluoride appears to be a metabolite of vinyl fluoride as it is found in the urine six days after exposure. The maximum value of the dipole moment is obtained under the following conditions. If the electric charges in the system are evenly distributed then the dipole moment of such a system is zero.

Microwave spectra of vinyl fluoride and its nine isotopic species were measured in order to establish the r s structure. Stark effect measurements for dipole moment determination were made using the balle flygare ftmw spectrometer at eastern illinois university eiu 13 14. Stark effect measurements of several low j transitions were carried out for the normal and three deuterated species.
