What is compressedairused for

Two-dimensional electronic spectroscopy (2DES) is an ultrafast laser spectroscopy technique studying electronic states in condensed-phase systems.

The transient absorption (TA) experiment enables the quantitative characterization of time-dependent absorption in an optically excited sample.

Laser-induced transient grating (LITG) spectroscopy is a pump-probe technique that utilizes laser interference instead of a single beam to excite the medium.

Fluorescence upconversion, time-correlated single-photon counting (TCSPC), and phosphorescence allow measuring fluorescence dynamics at different time scales.

The Z-scan experimental technique is used for measuring the nonlinear refractive index and nonlinear absorption coefficient of optical materials.

Two-dimensional infrared spectroscopy (2DIR) is a nonlinear infrared spectroscopy technique investigating vibrational modes in condensed-phase systems.

The propellant is a chemical that is not particularly dangerous to humans (if used correctly). When in the can it is in liquid form, and when let out of the can the decompression makes it a gas. The escaping of gas via the nozzle sets up an air current that draws in surrounding air, and thus most of the gas hitting your electronic components will literally just be air, encouraged by that initial movement of the propellant gas as it escaped the nozzle. It's a similar physical principle to the way those dyson fans work.

Anyway, I just wanted to point out that if you care about what you are releasing into the air, you may have been mislead by the way these are named. Indeed, the propellant used in them is considerably less damaging to the atmosphere than propellants commonly in use 50 years ago, but it is still not without harm, so it's worth knowing about.

Time- and angle-resolved photoemission spectroscopy (TR-ARPES) extends and complements conventional ARPES by adding femtosecond time-resolution.

Femtosecond stimulated Raman spectroscopy (FSRS) is a time-resolved spectroscopy technique for observing changes in the vibrational structure of optically excited molecular systems.

"Compressed air" is a marketing term for these products. If they literally did contain only air that is under pressure, they would probably last only one or two squirts. What they actually contain is a propellant substance - just like similar cans that contain deodorant, paint, etc. Except that these "canned air" products don't contain any paint or deodorant, only the propellant.

The principle of flash photolysis is analogous to the femtosecond transient absorption (TA) experiment but with the delay in a nanosecond–microsecond range.

Sum-frequency generation (SFG) spectroscopy is used to assess the vibrational properties of surfaces and interfaces with monolayer sensitivity.

Edit: some people are criticizing because they already knew this. If you already know this, that's fine, move on. Some people don't.

I keep seeing posts where people recommend using "compressed air" to clean computers and I've been wanting to point something out but the discussions get closed quickly (for rule 13, not because of the discussion of canned air).
