Hailed as the cutting edge in lecture hall technology when built, Pimentel Hall contains a lecture hall with seating for a few hundred, two bathrooms, and a setup area. Highlights of the lecture hall including a revolving stage, which allows for one professor to teach class, one to set up, and one to clean up, thus allowing the room to be used continuously despite the long setup times involved in chemistry lectures. Some professors have also taken advantage of the spinning stage for theatrical effect, rotating into the room with music playing.
The room also features stadium seating, and originally had numerous televisions suspended from the ceiling so students in the back could see what was going on.

Now, Pimentel continues to be among the most high tech of lecture halls, featuring a giant digital projector and webcast facilities. With webcasting, classes have been able to expand beyond the size of lecture hall seating capacities, as not all students are expected to view the lecture in person.
