2/19/2023 0 Comments Definition abscissa![]() The vertical value is the y-value or ordinate. The abscissa of a point is the signed measure of its projection on the primary axis, whose absolute value is the distance between the projection and the origin. See also: inelastic electron scattering background subtraction. Abscissa Definition and Meaning: Abscissa is the horizontal value on a graph. Note: Unit of peak area is unit of ordinate (the ordinate is often counts with unit '1') times unit of ~ (e.g. The radial coordinate of the second is plotted along the ~ this second electron is arbitrarily constrained to lie on the line connecting the nucleus and the first electron (along this direction, the inter-electronic interactions are largest). Abscissa - One of the elements of reference by which a point, as of a curve, is referred to a system of fixed rectilineal coordinate axes. Axes of graph showing normal distribution curve. Also called x-value (NOTE: The plural is abscissae or abscissas.) Webster Dictionary Meaning 1. ab-sisah the horizontal line in a graph along which are plotted the units of one of the variables considered in the study, as time in a time-temperature study. The vertical value is the y-value or ordinate. The ~ expresses the sequence of reactants, products, reaction intermediates and transition states and is usually undefined or only vaguely defined by the reaction coordinate (extent of bond breaking or bond making). Abscissa Abscissa is the horizontal value on a graph. If we mark on an axis of ~e a series of lengths proportional to angles, and trace ordinates which are proportional to sines or other trigonometrical functions, we get periodic curves of a harmonic character. In the very simplest elementary reactions it might correspond to the str etching or twisting of a particular bond, and be shown to a scale. The " reaction coordinate" plotted along the abscissa represents the changes in atomic coordinates as the system progresses from reactants to products. ![]() See the etymology of the corresponding lemma form.Latent variable versus observable variable Trumble and Angus Stevenson, editors (2002), “abscissa”, in The Shorter Oxford English Dictionary on Historical Principles, 5th edition, Oxford New York, N.Y.: Oxford University Press, →ISBN, page 8.įrom abscissus, perfect passive participle of abscindō ( “ tear away ” ).Ībscissa f ( genitive abscissae) first declension
