Title: ZEEMAN QUADRUPOLE SPECTRA OF p-CHLOROANILINE AND p-CHLOROBENZYLCHLORIDE
Creators: Meal, Harlan C.
Issue Date: 1954
Abstract: The Zeeman quadrupole spectra of $Cl^{35}$ in single crystals of p-chloroaniline and p-chlorobenzylchloride have been observed with a superregenerative spectrometer, using a pair of Helmholtz coils to supply the static magnetic field. Analysis of the spectrum observed with various field directions yields the following information: There are two sets of chlorine atoms in p-chloroaniline with differently oriented field gradients. The angle between the field gradient z axes is $79^{\circ}\pm 1^{\circ}$; the y axes are parallel. Both field gradients have the same asymmetry, $\eta=0.06\pm 0.03$. In p-chlorobenzylchloride there are four sets of chlorines (attached directly to the ring) which have differently oriented field gradients. The z axes are parallel to the edges of a rectangular pyramid with apex angles of $8^{\circ}$ and $67^{\circ}$, both $\pm1^{\circ}$. All four have the same asymmetry, $\eta=0.07\pm 0.02$ The bonds between the chlorine and the ring are calculated to have the following properties:
