Funds are requested to replace a broken FT-IR spectrometer’s base unit. The old instrument was used for every study conducted under the parent award due to the necessity of characterizing synthesized compounds by FT-IR spectroscopy and disseminating that data in the literature. The proposed purchase is of a Bruker ALPHA II base unit with a compact footprint that allows it to be housed inside a nitrogen- filled glovebox, thus enabling measurements to be done under inert atmosphere for air-sensitive samples. This setup matches the one used with the old instrument, a Bruker ALPHA I, whose diamond ATR and transmittance sampling modules are fully compatible with the ALPHA II and do not need replacing. Procuring the instrument and restoring the FT-IR experimental setup is critical to continuation of research in the parent award. Examples in the Research Strategy illustrate the importance of FT-IR in case studies.
