Related to relative reference: absolute reference relative referenceAn address or pointer that changes when the target item is moved or the relationship to it has changed. For example, in a spreadsheet, a cell with a relative reference changes its formula when copied elsewhere. Contrast with absolu...
The molecular formula of C20H32O6 was determined by the analysis of HRESIMS (high resolution electrospray ionization mass spectroscopy) data with five degrees of unsaturation. The 1H and 13C NMR signal patterns suggested a norditerpene endoperoxide core and established an isolated spin system, ...

Relative standard deviation and coefficient of variation | Relative standard deviation calculator, What is relative standard deviation, relative standard deviation formula definition
The average nominal oxidation state of carbon () is a function of the relative proportions of the elements in the chemical formula (see Methods). In Table 1 the proteins with the lowest values of are the mitochondrial homologs and those with the highest values of are the nuclear homologs. ...
