The architecture of a multi-user World-Wide Web NMR system has been described. The essential element of the system is the hardware and software interface between the NMR spectrometer and the World-Wide Web. The hardware is a UNIX computer equipped with an S-Bus digital input-output adapter and an external analog-digital converter. Software is a World-Wide Web server and a Common-Gateway Interface program written in C language. By employing the client/server paradigm, many near-simultaneous NMR sessions can take place via the well-known environment of the modern WWW browsers. The interface can be viewed as an inexpensive migration path to upgrading older instrumentation offering much improved capabilities, e.g., faster sampling rates.
