SPVIEW is a multi-platform Java application that allows graphical assignment of high-resolution molecular spectra. It is possible to load, display and manipulate experimental and simulated spectra (XY ASCII format) as well as stick spectra in various formats (including HITRAN format). Lines can be assigned graphically using the mouse. Assignments can also be modified or removed. Local simulations can be performed in order, for instance, to help assignment in partly resolved line clusters. SPVIEW is also able produce peak lists from an experimental spectrum. This tool can be used in conjunction with XTDS, which is a Java front-end to the different programs implementing the tensorial formalism developed in our group. XTDS allows the simulation and analysis of any polyad system for molecules of various symmetries (Td and Oh spherical tops like CH4 and SF6, C2v and C4v quasi-spherical tops like SO2F2 and SF5Cl, D2h molecules like C2H4). Its capabilities have been recently augmented and improved.
