✦ Synopsis

Visual computer languages exploit the natural language of diagrams and pictures to provide a simple and intelligible approach to programming. Unfortunately, it is difficult to provide them with a formal syntax and semantics. In this paper we show how the RCC spatial calculus can be used to provide an unambiguous, formal description of such languages by systematically describing the syntax of Pictorial Janus.

## Abstract We present the application of a 2D broadband homodecoupled proton NMR experiment to the visualization of enantiomers. In a chiral environment, the existence of diastereoisomeric intermolecular interactions can yield—generally slight—variations of proton chemical shifts from one enantiom
