WebAn attenuated total reflectance infrared spectroelectrochemical (ATR-IR-SEC) technique has been developed that uses a surface-proximal doped Si ATR crystal as both the ATR optical element and the working electrode. This allows redox processes of monolayers of molecules attached to the Si surface to be probed through changes in their molecular vibrations as … Web1 Module 4; Making and Naming Ionic Compounds Introduction Elements/Compounds Matter is anything that has mass and occupies space. Types of matter can be organized into several different categories. Pure substances are those that cannot be physically separated into different substances. Compounds are substances that can be separated into simpler …
