C 1 NQR Study of 4 , 4 , - Dichlorobenzophenone *
نویسندگان
چکیده
Pulsed NQR has been used to get information about the two phase transitions (PT) in 4,4'-dichlorobenzophenone. The measurements of the NQR spectrum and spin-lattice relaxation suggest that the PT's correspond to a normal-incommensurate and to the lock-in of a commensurate structure at lower temperature. Strong hysteresis has been observed, which could be assigned to memory effects produced by defect migrations.

Phase Transitions in 4 , 4 ' - Dichlorobenzophenone as Studied by 3 SC 1
The temperature dependence of 35C1 NQR frequencies in 4,4'-dichlorobenzophenone was mea sured between 9.3 and 372 K by the pulse Fourier-transform method. Successive phase transitions were observed at 189 and 194 K. Concerning these phase transitions, the curious thermal hysteresis phenomenon found in a previous NQ R experiment was not reproduced in the present study. It also follows that NQ R...

The C1 NQR spectra of the two phases (phases I and II) of 2,3-dichloro-l,4-naphthoquinone were studied from 77 to 394 K. The crystal structure determination of the triclinic phase (phase I) was refined by single crystal X-ray diffraction. Phase I crystallizes in the space group C/-P1. The unit cell (Z = 4) has the dimensions a = 1614.3(4) pm, 6 = 828.1 (3) pm, c = 733.2(3) pm, a = 67.02(l)°, /?...
متن کاملProbing the Electronic Structure of Y - B a - C u - O Superconductors by Copper NQR/NMR
The paper discusses some N Q R / N M R studies performed on Y B a C u O superconductors at the University of Zürich. It is shown how the resonance methods can yield information on electronic properties of quite different character. The review deals with: (1) the temperature and pressure dependence of Cu N Q R frequencies in YBa 2 Cu 4 O g (1-2-4); (2) an NQR study of the properties of Ca substi...

2,3,4,4-Tetrachloro-l-oxo-l,4-dihydronaphthaline, ß-TKN, crystallizes in the orthorhombic space group D ^ P n m a with Z = 4, and the C1 N Q R spectrum consists of three lines with an intensity ratio of 2:1:1. The crystal structure of 2,2,3,4-tetrachloro-l-oxo-l,2-dihydronaphthaline, a-TKN, is described in literature as belonging to the polar space group C ^ P ^ with Z = 2. In contradiction to ...
