Using their specialized coil, the researchers measured the chemical shifts for fluorine nuclei in various compounds well enough to tell one substance from another.
A quantitative understanding of microscopic characteristics of hydrogen bonds in various compounds is quite important for the deep study of structure-property relationships of functional crystals.
The aim of the chapter is to survey the strong attractive intramolecular X ← Y interactions of 1,5-type occurring between terminal main-group 14 16 centers (X) and electron-rich atoms Y (Y = O, S, NR, and others) in various compounds resulting in significant stabilization of cis-s-cis structure of these molecules.
Environ Health Perspect 122 255 261; http://dx.doi.org/10.1289/ehp.1307545 Arsenic is a widely distributed semimetallic element that occurs naturally in various compounds in the crust of the earth.
Positive regression coefficients (Fig. 3) were obtained in the region of 3597 3440 cm−1 of the spectrum dominated by the stretching vibration of the O-H bond in various compounds, making an interpretation of this region difficult.
As multiplets in various compounds have different C isotope shifts and C fractional enrichments, the line shape distortion varies across the spectrum and can therefore not be accommodated by a global line shape distortion factor.
A starting point could be the proper understanding of the term "Cryo-" in the various compound words found in various disciplines.
In other field test research conducted between 2003 and 2005 in North America and Europe, nZVI was effective in treating various compounds in groundwater, including chlorinated solvents and Cr VI) (Macé et al. 2006).
In the 19th century various compound characters were also used, similar to Japanese, either imported or formed on the same principles, such as for qiānwǎ (kilowatt) or for.
In its various compounds, potassium makes up about 2.6% of the weight of the Earth's crust and is the seventh most abundant element, similar in abundance to sodium at approximately 1.8% of the crust.
