Hydrogen, known affectionately yet confusingly as "the proton" to NMR spectroscopists, can be regarded as the mother nucleus of high-resolution study. Its place and contribution to organic chemistry are well documented and its use is extensive, both because of its early emergence in the ...
2022. Indication of hydrogen and oxygen stable isotopes on the characteristics and circulation patterns of medium-low temperature geothermal resources in the Guanzhong Basin, China. Journal of Groundwater Science and Engineering, 10(1): 70-86. doi: 10.19637/j.cnki.2305-7068.2022.01.007 ...
2H is often called deuterium, and3H is referred to as tritium. The atomic mass of natural hydrogen (1.0080) exceeds that of1H because of the admixture of deuterium: In the following chart, which nuclei are isotopes of one chemical element? Can you give the element's name? Which nuclei hav...
Stable isotopes of hydrogen (δ2H) and oxygen (δ18O) provide important quantitative measures of lake hydrology and water balance, particularly in lakes where monitoring of fluxes is incomplete. However, little is known of the relative effects of seasonal variation in water isotopes on estimates of...
ETS is the source of numerous toxic and carcinogenic contaminants in indoor environments; some of the major ones are acetaldehyde, acetone, acrolein, ammonia, carbon dioxide, carbon monoxide, formaldehyde, hydrogen cyanide, nitrogen oxides, and pyridine in vapor/gas phase, and aniline, benzo[a]pyr...

Researchers at Instituut voor Kern- en Stralingsfysica in Belgium and The University of Manchester, in collaboration with other institutes worldwide, have recently carried out a study aimed at measuring the size of the nucleus (i.e., nuclear charge radiu
It is then the object of this paper to theoretically study the hydrogen isotopes H-4,H-7 with the Gamow shell model and to perform, to our knowledge, the first direct calculation of unbound resonance hydrogen isotopes up to H-7. As the Gamow shell model includes both continuum coupling ...
