THE CORRECTION OF HYDROGEN MOLECULAR-EXCITATION TO THE 3T BETA-SPECTRUM
Using a modified variational wave function of Michels type the second excited 1Σ state of HeH+ ion is calculated, and consequently its contribution to the tritium molecule β-spectrum is estimated. In addition to this, the source temperature effect as well as the effect of different isotopic compositions such as T2, TD and TH in the hydrogen molecules are also discussed in detail.
Objective To control the quality of Herba Leonuri by studying the content of stachydrine hydrochloride in different parts of it. Method A HPLC method was developed for the content detetmination of stachydrine hydrochloride in flower, stem, leafage from Herba Leonuri. Spherisorb SCX colum was used with mobile phase of 20 mmol/L sodium dihydrogen phosphate (containing 0.04% triethylamine and 0.15% phosphoric acid). The colum temperature was 25 ℃, the detective wavelength was 192 nm. Results Stachydrine hydrochloride content was the highest in leafage and the lowest in stem. Conclusion To ensure the quality of Herba Leonuri, it is significant to choose medical material with more leafage.
