deuterated water वाक्य

Transpiration can be measured by direct injection of deuterated water into the base of the tree, trapping all water vapor transpired from the leaves and measuring the subsequent condensate.
Simple NMR spectra are recorded in solution, and solvent protons must not be allowed to interfere . deuterated water, D 2 O, deuterated acetone, ( CD 3 ) 2 CO, deuterated methanol, CD 3 OD, deuterated dimethyl sulfoxide, ( CD 3 ) 2 SO, and deuterated chloroform, CDCl 3.
An example of the use of isotopic labeling is the study of phenol ( C 6 H 5 OH ) in water by replacing common hydrogen ( deuterated water ( water containing D 2 O in addition to the usual H 2 O ), the substitution of deuterium for the hydrogen is observed in phenol's hydroxyl group ( resulting in C 6 H 5 OD ), indicating that phenol readily undergoes hydrogen-exchange reactions with water.
Where WU is the water use in kilograms / day, M is the mass of deuterated water injected in grams, T is the final day of the experiment, C i is the concentration of deuterium at time interval i in grams / kilogram, and ?t i is the length of time interval i in days . Although the calculated water use via thermal dissipation probing of some tropical plants such as bamboos correlates strongly with measured water use found by tracking D 2 O movement, the exact values are not the same.
