When Is a Vibrational Mode of a Molecule Raman Active

question 4

Multiple Choice

When is a vibrational mode of a molecule Raman active?

• A) When the vibrational mode has the same symmetry as a component of the molecule's electric dipole moment vector.
• B) When the vibrational mode has the same symmetry as a component of the molecule's polarizability.
• C) Vibrational modes of molecules are Raman active only; they cannot be IR active at the same time

Definitions:

Fixed-Interval

In operant conditioning, a fixed-interval schedule is a reinforcement pattern where a response is rewarded only after a specified amount of time has elapsed, leading to a response pattern where actions are more frequent as the time for reward approaches.

Punishment

An event that decreases the behavior it follows.

Negative Reinforcers

Stimuli that, when removed after a behavior, increase the likelihood of that behavior being repeated in the future.

Generalization

The process of applying the outcome of a particular instance to a broader range of similar instances.
