Explanation:
Two-dimensional nuclear magnetic resonance spectroscopy (2D NMR) is a set of nuclear magnetic resonance spectroscopy (NMR) methods which give data plotted in a space defined by two frequency axes rather than one. Types of 2D NMR include correlation spectroscopy (COSY), J-spectroscopy, exchange spectroscopy (EXSY), and nuclear Overhauser effect spectroscopy (NOESY). Two-dimensional NMR spectra provide more information about a molecule than one-dimensional NMR spectra and are especially useful in determining the structure of a molecule, particularly for molecules that are too complicated to work with using one-dimensional NMR.
The first two-dimensional experiment, COSY, was proposed by Jean Jeener, a professor at the Université Libre de Bruxelles, in 1971. This experiment was later implemented by Walter P. Aue, Enrico Bartholdi and Richard R. Ernst, who published their work in 1976
Markup<span> is the ratio between the </span>cost<span> of a </span>good<span> or </span>service<span> and its selling price. It is expressed as a percentage over the cost. A markup is added onto the total cost incurred by the producer of a good or service in order to cover the costs of doing business and create a </span>profit<span>. The total cost reflects the total amount of both </span>fixed<span> and </span>variable expenses<span> to produce and distribute a </span>product. <span>Markup can be expressed as a fixed amount or as a percentage of the total cost or selling price.</span> Retail markup<span> is commonly calculated as the difference between </span>wholesale<span> price and retail price, as a percentage of wholesale. Other methods are also used.</span>
