Multidimensional spectra are collected ``directly'' by scanning OPAs against each-other. \vspace{\baselineskip} \\ This strategy is... \begin{itemize} \item slow (must directly visit each pixel) \item fragile (many crucial moving pieces) \end{itemize} but! It is incredibly flexible. \end{frame} \begin{frame}{Bandwidth} MR-CMDS has no bandwidth limit! \vspace{\baselineskip} \\ There is just the small matter of making the source continuously tunable... \adjincludegraphics[width=\textwidth]{opa/OPA_ranges} \end{frame} \begin{frame}{Selection rules} MR-CMDS can easily collect data without an external local oscillator. \vspace{\baselineskip} \\ This means...
