N-(4-Chlorophenyl)succinamic acid
In the title compound, C10H10ClNO3, the conformation of the amide O atom and the carbonyl O atom of the acid segment are anti to each other and further, they are anti to the H atoms of their adjacent –CH2 groups. The C=O and O—H bonds of the acid group are in the syn position relative to each other. In the crystal, molecules are packed into infinite chains through intermolecular N—H⋯O and O—H⋯O hydrogen bonds
ANOMALOUS GAUGE BOSON INTERACTIONS
We discuss the direct measurement of the trilinear vector boson couplings in
present and future collider experiments. The major goals of such experiments
will be the confirmation of the Standard Model (SM) predictions and the search
for signals of new physics. We review our current theoretical understanding of
anomalous trilinear gauge boson self-interactions. If the energy scale of the
new physics is TeV, these low energy anomalous couplings are expected
to be no larger than . Constraints from high precision
measurements at LEP and low energy charged and neutral current processes are
critically reviewed.Comment: 53 pages with 17 embedded figures, LaTeX, uses axodraw.sty, figures

N-(2-Chlorophenyl)succinamic acid
The conformations of the N—H and C=O bonds in the amide segment of the structure of the title compound {systematic name: 3-[(2-chlorophenyl)aminocarbonyl]propionic acid}, C10H10ClNO3, are trans to each other, while the conformation of the amide H atom is syn to the ortho-chloro group in the benzene ring. Further, the conformations of the amide O atom and the carbonyl O atom of the ester segment are also trans to the H atoms attached to the adjacent C atoms. In the crystal structure, molecules are packed into infinite chains through intermolecular N—H⋯O and O—H⋯O hydrogen bonds
2,4-Dimethylphenyl benzoate
The crystal structure of the title compound (24DMPBA), C15H14O2, resembles those of 4-methylphenyl benzoate, 2,3-dimethylphenyl benzoate and other aryl benzoates, with similar bond parameters. The central –O—C—O– group in 24DMPBA makes dihedral angles of 85.81 (5) and 5.71 (13)°, respectively, with the benzoyl and phenyl rings, while the two aromatic rings form a dihedral angle of 80.25 (5)°. The molecules are packed with their axes parallel to the a-axis direction
Experimental measurement of stress at a four-domain junction in lead zirconate titanate
A junction between two lamellar bands of ferroelectric domains in a lead zirconate titanate (PZT) ceramic is analysed using Kikuchi diffraction patterns in the transmission electron microscope. Indexing of the diffraction patterns allowed the determination of the 3D relative orientation of the 4 different domains at the junction and thus the characterisation of the domain boundaries. The local c/a ratio could also be determined from the misorientations at the domain boundaries. Analysis of the data showed that large stresses were concentrated at the junction, and that this is inevitable at such band junctions. Such stress concentrations could act as nuclei for cracking of the ceramic under additional loading in service, perhaps particularly as a consequence of extended electromechanical cycling. Moreover, the stresses would increase with increasing c/a making the issues all the more serious for Ti-rich compositions having larger c/a ratios
2-Methylphenyl 4-methylbenzoate
The conformation of the C=O bond in the title compound 2MP4MBA, C15H14O2, is anti to the ortho-methyl group in the phenoxy ring. The bond parameters in 2MP4MBA are similar to those in 3-methylphenyl 4-methylbenzoate (3MP4MBA), 4-methylphenyl 4-methylbenzoate (4MP4MBA) and other aryl benzoates. The dihedral angle between the two aromatic rings in 2MP4MBA is 73.04 (8)°
N-(4-Methylphenyl)succinimide
In the molecule of the title compound, C11H11NO2, the dihedral angle between the aromatic ring and the amide segment is 57.3 (1)°
2,3-Dimethylphenyl benzoate
The structure of the title compound (23DMPBA), C15H14O2, resembles those of phenyl benzoate (PBA), 3-methylphenyl benzoate (3MePBA), 2,6-dichlorophenyl benzoate (26DCPBA) and other aryl benzoates, with similar bond parameters. The dihedral angle between the benzene and benzoyl rings in 23DMPBA is 87.36 (6)°, compared with values of 55.7° in PBA, 79.61 (6)° in 3MePBA and 75.75 (10)° in 26DCPBA. The molecules in 23DMPBA are packed into a chain-like structure in the direction of the a axis
Methyl N-(2,3-dichlorophenyl)succinamate
The asymmetric unit of the title compound, C11H11Cl2NO3, contains two independent molecules. In both the molecules, the H atoms of the adjacent –CH2 groups of the acid segments orient themselves away from the amide O and the carbonyl O atoms. The C=O and O—CH3 bonds of the ester group are in syn positions with respect to each other. In the crystal, the molecules are linked into infinite chains through intermolecular N—H⋯O hydrogen bonds
