Witryna30 sty 2024 · The higher 1700 cm-1 indicates a large dipole moment change. It is easier to bend a molecule than stretch it, hence stretching vibrations have higher frequencies and require higher energies than bending modes. The finger print region is a region from 1400-650 cm-1. Each molecule has it's own characteristic print and is often … WitrynaImpurities can be classified into the following categories: • Organic impurities (process- and drug-related) • Inorganic impurities • Residual solvents Organic impurities can arise during the manufacturing process and/or storage of the new drug substance. They can be identified or unidentified, volatile or non-volatile, and include:
