(quantum mechanics)
Integral over the coordinates of two identical particles which can be thought of as the interaction between a given state and a second state in which the coordinates of the particles are exchanged.

In the following paragraphs, we will compare this simple integrative approach to kinetic modeling using three different approaches, which are two-site exchange differential model, two-site exchange integral model, and multisite exchange integral model.
Hence, when passing from 2SIM to a multisite exchange integral model (MSIM), the PYR input function (4)--represented in its differential form--needs to include all of the metabolic exchange rates:
Multisite kinetic modeling of [sup.13]C metabolic MR using [1-[sup.13]C]pyruvate
The asymptotic behavior at the Bethe Ridge was used to simplify the calculation and to provide values for the exchange integral.
