EPR in-situ reaction tank for vacuum, atmosphere, illumination and variable-temperature reaction

Abstract

The invention discloses an EPR in-situ reaction tank for vacuum, atmosphere, illumination and variable-temperature reaction. The EPR in-situ reaction tank comprises an outer-layer pipe, an inner-layer pipe, a first connector, a second connector and a four-way connector which are coaxially arranged, the upper end of the outer-layer pipe is open, the lower end of the outer-layer pipe is closed, the two ends of the inner-layer pipe are open, a first wedge-shaped rubber sleeve is arranged at the upper end of the outer-layer pipe, a first wedge-shaped opening is formed in the upper end of the first connector, the upper end of the first connector is connected with the lower end of the four-way connector, a second wedge-shaped rubber sleeve is arranged at the upper end of the inner-layer pipe, a second wedge-shaped opening is formed in the upper end of the four-way connector, the upper end of the four-way connector is connected with the lower end of the second connector, and an air inlet is formed in the upper end of the second connector, and air outlets are formed in the left and right ends of the four-way connector. The straight electron paramagnetic resonance sample tube can replace a traditional straight electron paramagnetic resonance sample tube, in-situ reaction with gas participation, illumination and variable temperature can be conveniently carried out, and good test conditions can be provided for reaction information detection of a sample under the conditions of atmosphere, illumination, variable temperature and the like.

Description

technical field [0001] The invention relates to the technical field of EPR in-situ atmosphere reaction pools, in particular to an EPR in-situ reaction pool for vacuum, atmosphere, light and variable temperature reactions. Background technique [0002] Electron Paramagnetic Resonance (EPR) spectroscopy is a spectroscopic method that detects unpaired electrons or paramagnetic substances and can provide microscopic information such as electrons, orbitals, and nuclei. Such as: free radicals, diradicals or polyradicals, single atoms, simple metals, triplet molecules, transition metal ions and rare earth ions, lattice defects in solids, complexes, doping materials, atoms with odd electrons and singlet Electron molecules etc. Due to the establishment of various new technologies and methods of electron paramagnetic resonance experiments such as modern pulse EPR, transient EPR, and imaging EPR, electron paramagnetic resonance EPR technology has been widely used in physics, chemistry...
