在室温下，用活塞-气缸装置测定了新戊烷、双环[2.2.2]辛烷和金刚烷的压缩行为。发现在每个系统中的相变。阶段I（低压）压缩和减压运行平均值的结果拟合为形式为− ΔV / V0 = a0 + a1 P + a2 P2的方程。甲烷的文献结果（在77°K下）也适合于该方程。获得以下结果（每立方米）：甲烷，相I，a0 = 3.64 × 10−3，a1 = 4.98 × 10−2，a2 = − 3.46 × 10−3，− ΔV / V0（跃迁）= 0.022;新戊烷，I相，a0 = 0.000，a1 = 4.08 × 10−2，a2 = − 2.60 × 10−3，− ΔV / V0在6.5 ± 0.5 kbar时，（跃迁）=0.049;双环[2.2.2]辛烷，相I，a0 = 0.000，a1 = 2.65 × 10−2，a2 = − 1.04 × 10−3，在9.1 ± 0.7 kbar时，− ΔV / V0（跃迁）= 0.022。金刚烷，I相，a0 = 0.000，a1 = 2.59 × 10−2，a2 = − 2.04 × 10−3，4.1 ± 0.5 kbar时− ΔV / V0（跃迁）= 0.014。N-6的阱深最小距离和排斥指数
The compressive behavior of neopentane, bicyclo[2.2.2]octane, and adamantane has been measured at room temperature in a piston cylinder apparatus. A phase transition was found in each system. The results for phase I (low pressure) for the average of compression and decompression runs were fit to an equation of the form − ΔV / V0 = a0 + a1P + a2P2. Literature results for methane (at 77°K) were also fit to this equation. The following results were obtained (per kilobar): methane, phase I, a0 = 3.64 × 10−3, a1 = 4.98 × 10−2, a2 = − 3.46 × 10−3, − ΔV / V0 (transition) = 0.022; neopentane, phase I, a0 = 0.000, a1 = 4.08 × 10−2, a2 = − 2.60 × 10−3, − ΔV / V0 (transition)=0.049 at 6.5 ± 0.5 kbar; bicyclo[2.2.2]octane, phase I, a0 = 0.000, a1 = 2.65 × 10−2, a2 = − 1.04 × 10−3, − ΔV / V0 (transition) = 0.022 at 9.1 ± 0.7 kbar. adamantane, phase I, a0 = 0.000, a1 = 2.59 × 10−2, a2 = − 2.04 × 10−3, − ΔV / V0 (transition) = 0.014 at 4.1 ± 0.5 kbar. The well‐depth, minimum distance, and repulsive exponents of a “N‐6” ...
