The reasons for the presence of spurious modes in plane isoparametric elements are examined. Eigenvalue and eigenvector analyses of stiffness matrices for single elements and unconstrained and constrained meshes reveal the types of mechanisms and near-mechanisms that can be expected when reduced or

Two-dimensional (2D) correlation techniques were applied to microwave Fourier transform (MWFT) spectroscopy. A threepulse sequence supplied with a phase cycle acting as a double-quantum filter as well as a two-pulse "CO%" sequence were found to be useful for the correlation of connectivities between
Two-dimensional Fourier-transform ESR spectra from a complex fluid characterized by very short free induction decay times are reported. They provide enhanced resolution to dynamic molecular structure compared to conventional cw-ESR spectra which are inhomogeneously broadened by the macroscopic disor
