The strongest superbases are formed in this state by collisions during mass spec. For 10 points each:
[10e] Name this state of matter in which molecules are far enough apart to be free of solvent effects.
ANSWER: gas phase [or gaseous; accept gas-phase acidity gas-phase basicity or gas phase proton affinity]
[10m] Gas phase acidity is measured in this part of a spectrometer, which may be quadrupolar or dipolar (“DYE-polar”). In FT–MS, ions produce a free-induction decay while in this component by oscillating at the cyclotron frequency.
ANSWER: ion trap [or Penning trap]
[10h] Superbases can also be studied under this condition, where they may be ionized via electrospray or by directing them into a corona discharge with a carrier gas like helium. Spectrometers operating under this condition are prime candidates for miniaturization, as they lack bulky turbos or rotors.
ANSWER: high pressure [or atmospheric pressure; accept ambient pressure or ambient conditions] (ESI is done at atmospheric pressure.)
