A general theoretical treatment of intensity perturbations is given for the vibration–rotation lines of asymmetric rotor. The nonlinear XYX molecules are specially treated, and for this case a new formula is derived for the correction F factors of the intensities. A good agreement is obtained with other authors for the bands ν1 and ν2 of H2O;, and new information is derived for the band ν3 of the same molecule.

Abstract The use of temporal modes in quantum optics and their relation to the energy-momentum tensor is analyzed from first principles. We show the approximations under which this approach can be used for the quantum description of electromagnetic waves propagating in non-linear optical media.

The decay of an ensemble of two-level molecules is described by a quantum-mechanical formalism involving single molecule operators. Equations of motion are obtained for the operators by means of a pertubative analysis, containing spontaneous decay terms and those that connect different molecules. A travelling wave solution is presented for the relaxation of one-dimensional chain of molecules.

Abstract Polarization measurements in atomic cascades are described by following a quantum mechanical analysis. Violation of Bell inequalities for these measurements may follow from correlations introduced by the measurement process and not from action at a distance.

Abstract The phenomena of delayed spontaneous emission in molecular beam-foil experiments, is interpreted as Dicke photon trapping.

Abstract The space dependence of the photon statistics in possible interference experiments of squeezed and coherent beams of radiation is studied. We predict that spatial periodic changes from subpoisson to superpoisson photon statistics may be observed by a detector, which is moved perpendicular to the squeezed beam

The theory of photon trapping is presented and discussed for collection of molecules. The main features of the phenomenon are given on the basis of symmetry considerations. General equations of motion are developed for a multimolecular system sharing a single excitation.

Abstract The possibility to produce a squeezed state by a phase conjugated mirror is discussed. The quantum noise obtained in a phase conjugated mirror is due to the fact that only the reflected beam is measured. By adding, in interference experiments, the reflected beam to the transmitted one, in a degenerate four-wave mixing scheme, squeezed states are obtained. The possibility to use these phenomena for the production of squeezed states is discussed.

Abstract The reduction of the amount of quantum noise in modulation experiments by the use of two-mode squeezed states is discussed. It is shown that by the use of squeezed radiation instead of coherent radiation, the amount of quantum noise at the modulated frequency can be reduced by many orders of magnitude.
