Pentane (C₅H₁₂) is a saturated hydrocarbon (C_nH_2n+2) with 42 electrons and it has two isomers, isopentane and neopentane. We consider all the three gases in this chapter. Selected properties of the three molecules are shown in Table 138.1.

138.1 SELECTED REFERENCES FOR DATA

Selected references for data on C₅H₁₂ and its isomers are shown in Table 138.2.

138.2 MOMENTUM TRANSFER CROSS SECTIONS

See Table 138.3. Gee and Freeman (1983) suggest a relationship of the form

$$Q_{\text{M}}=Q_0{\epsilon }^{-n}$$ (138.1)

where Q₀ is a constant and n the ...
