Dipole Moment Of Vinyl Fluoride

I was checking dipole moment orders and came across a very peculiar result.

Dipole moment of vinyl fluoride.

Vinyl fluoride is classified as an iarc group 2a carcinogen likely to cause cancer in humans. Microwave spectra of vinyl fluoride and its nine isotopic species were measured in order to establish the r s structure. Very small volume fraction 0 035 both inclusion. Stark effect measurements of several low j transitions were carried out for the normal and three deuterated species the dipole moment of the normal species of vinyl fluoride is μ a 1 284 0 004 μ b 0 712 0 012 and μ total 1 468 0 007 d and makes an angle.

Voltages of up to 5 kv were applied across two steel mesh plates spaced about 31 cm apart above and below the fabry perot cavity of the spectrometer and electric field calibration was. If the electric charges in the system are evenly distributed then the dipole moment of such a system is zero. Its molecular dipole moment is 1 4 debye and heat of vaporization is 361 kj kg. Dt cramb mcl gerry w lewis bevan determination of rotational constants using nuclear quadrupole hyperfine structure.

Molecules with non zero dipole moment are called polar. 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. Stark effect measurements for dipole moment determination were made using the balle flygare ftmw spectrometer at eastern illinois university eiu 13 14. Fluoride appears to be a metabolite of vinyl fluoride as it is found in the urine six days after exposure.

The microwave spectrum and dipole moment of vinyl iodide obtained using a computer controlled spectrometer j. Stark effect measurements of several low j transitions were carried out for the normal and three deuterated species. Methyl fluoride ce ch3f has lesser dipole moment than methyl chloride ce ch3cl but hydrofluoric acid ce hf has more dipole moment than hydrochloric acid ce hcl. 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.

The maximum value of the dipole moment is obtained under the following conditions. The conformers are designated as gauche trans axial etc. Microwave spectra of vinyl fluoride and its nine isotopic species were measured in order to establish the r s structure. Its critical point is at 54 8 c 328 k and 5 24 mpa.

An example of such a molecule is water h 2 o h 2o h 2 o. Dipole moments of individual conformers rotational isomers are given when they have been measured. In some cases an average value obtained from measurements on the bulk gas is.
