Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Remote symmetry breaking in Jäger‐type iron(II) complexes shifts stepwise spin crossover (SCO) profiles to continuous profiles with transition temperatures around room temperature. In a bottom‐up approach, we studied the feedback of slight molecular modifications on the spin crossover (SCO) properties of otherwise structurally conserved iron(II ...

Crystal Structure of [Sr(SeC2H)2(NH3)2], Solved and Refined From Powder X‐Ray Diffraction Data
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The synthesis and crystal structure of [Sr(SeC2H)2(NH3)2] are described, the first alkaline earth metal compound with the recently discovered –SeC2H anion. The title compound releases NH3 even under ambient conditions, so its crystal structure had to be determined from moderately resolved X‐ray powder diffraction data.

Physiotherapy, 1991
Summary Infra-red therapy has been used in clinical practice for a considerable period of time; there are, however, a limited number of studies which evaluate the efficacy of this modality in the management of clinical conditions. This review considers the physical behaviour, physiological effects, the efficacy and hazards of infra-red therapy.

Spectrochimica Acta, 1950
A discussion of the performance characteristics of an infra-red microspectrometer is given in terms of the cross-sectional area and minimum volume, V, which can be observed with satisfactory signal-to-noise ratio. Methods of increasing the ratio of measured absorption to spectrometer noise are discussed and five ways are enumerated.

Journal of the Optical Society of America, 1948
A pupillometer for measuring pupil diameters in total visual darkness has been constructed. It consists of an infra-red electron telescope arranged to observe the eye from a distance of about six inches. An attached light source irradiates the eye with invisible infra-red radiation.

The Polarization of Infra-Red Radiation
Journal of the Optical Society of America, 1948A transmission polarizer for the near infra-red is described, which is small and compact and can be mounted on a spectrometer without alteration of the existing optical system. It employs a pile of self-supporting selenium films, each approximately 4 microns thick.

Polarization of Infra-Red Radiation
Nature, 1947A METHOD of making thin selenium films with free surfaces has been devised, and this has enabled us to construct a pile of selenium films which polarize a beam of radiation falling on the plates at the appropriate angle. The transmitted beam is the one which is used, and a high degree of polarization (with very little loss of efficiency) is obtained ...

Abstract Three rations, 350 ml. distilled water, 250 ml. distilled water plus 96·5 g carbohydrate, and 350 ml. distilled water plus 150 ml. sea water, were given daily for 3-day periods to six subjects receiving no other food or drink. The experiment was fully ‘crossed-over' and was carried out in a constant environment.
