The increasing importance and intriguing optical characteristics of plasmonic nanostructures have stimulated research interests in science, engineering and medicine to design and fabricate metal nanoparticles/nanostructures with a variety of shapes. In this presentation, first, I will discuss the design, fabrication and optical characterization of plasmonic metal nanostructures that have multiple plasmon resonances in the visible and near infrared regions.

Pulsed multidimensional experiments, daily business in the field of NMR spectroscopy, have been demonstrated only relatively recently in IR spectroscopy. Similar as nuclear spins in multidimensional NMR, molecular vibrations are employed in multidimensional IR experiments as probes of molecular structure and dynamics, albeit with femtosecond time resolution. Different types of multidimensional IR experiments have been implemented, resembling basic NMR experiments such as NOESY, COSY and EXSY.
