Which outcome occurs when increased thermal energy excites molecular vibrational modes within a crystal?

💡 Explanation

Increased vibrational modes lead to greater bond movement which causes increased infrared absorption because bonds vibrate at infrared frequencies. Therefore, infrared radiation absorption increases rather than decreased electrical conductivity, because conductivity changes from electron movement, or other options.
