In the second installment of “The Big Review,” we discuss the physical mechanism behind how molecules absorb infrared (IR) radiation. Because light can be thought of as a wave or a particle, we have two equivalent pictures of IR absorbance. We also discuss the quantum mechanics behind IR absorbance, and how this leads to the different peak types observed in IR spectrum.
Data process mapping is an effective way to identify data integrity vulnerabilities and remediate them. A modified example published by the Active Pharmaceutical Ingredients Committee (APIC) is reviewed critically. Can it be simplified?
