Deuterated chloroform is a general purpose NMR solvent, as it is not very chemically reactive and unlikely to exchange its deuterium with its solute, [9] and its low boiling point allows for easy sample recovery. It, however, it is incompatible with strongly basic, nucleophilic, or reducing analytes, including many organometallic compounds.
Deuterated solvents are a group of compounds where one or more hydrogen atoms are substituted by deuterium atoms. These isotopologues of common solvents are often used in nuclear magnetic resonance spectroscopy .
The Sri Lankan Rupee (Sinhala: රුපියල්, Tamil: ரூபாய்; symbol: රු (plural) in English, රු in Sinhala, ௹ in Tamil; ISO code: LKR) is the currency of Sri Lanka. It is subdivided into 100 cents ( Sinhala : සත , Tamil : சதம் ), but cents are rarely seen in circulation due to their low value.
This is a list of tables showing the historical timeline of the exchange rate for the Indian rupee (INR) against the special drawing rights unit (SDR), United States dollar (USD), pound sterling (GBP), Deutsche mark (DM), euro (EUR) and Japanese yen (JPY). The rupee was worth one shilling and sixpence in sterling in 1947.

Decimalisation or decimalization (see spelling differences) is the conversion of a system of currency or of weights and measures to units related by powers of 10.. Most countries have decimalised their currencies, converting them from non-decimal sub-units to a decimal system, with one basic currency unit and sub-units that are valued relative to the basic unit by a power of 10, most commonly ...
The chloroform molecule can be viewed as a methane molecule with three hydrogen atoms replaced with three chlorine atoms, leaving a single hydrogen atom. The name "chloroform" is a portmanteau of terchloride (tertiary chloride, a trichloride) and formyle, an obsolete name for the methylylidene radical (CH) derived from formic acid. [citation ...
Deuterated benzene is a common solvent used in NMR spectroscopy. It is widely used for taking spectra of organometallic compounds, which often react with the cheaper deuterated chloroform. [3] A slightly more exotic application of C 6 D 6 is in the synthesis of molecules containing a deuterated phenyl group.
