I'm doing research for my professor, and I'm trying to figure out which measurement I need to use. I want to come up with ideas on DAC using MOF or other possible materials that might filter particles like zeolites. What I've read on O2, it's kinetic diameter is larger than CO2, but the molecular diameter of O2 is smaller. Is this correct? How do you measure the size of a molecule? Because they are 3-dimensional and can make all kinds of shapes. What measurements should I look for?
Kinetic diameter is more of a likelihood that a particle will collide with another; it's more of a "size of target" than a literal size of the molecule. Here's an article that walks through some sample calculations and has a chart of a number of kinetic diameters.
molecular diameter: actual diameter of a molecule
kinetic diameter: diameter of the "target size" within which another molecule will collide
