“…At the outer surface of the container, copper sockets were soldered to the wires to hold temperature sensors. The liquid methanol sample was admitted into the container of the measuring cell under 4 He gas. The helium gas was used to improve the heat exchange between the sample and the container.…”

“…At varying temperature and pressure, methanol displays more equilibrium phases than ethanol [4][5][6]13]. Polymorphism of the crystalline phases of methanol is governed by its H bonds which are stronger than the dispersive molecular interactions and by its simpler molecular structure in comparison to ethanol.…”

“…The simple structure of the methanol molecule shows up most obviously in its properties [2][3][4][5][6][7][8][9][10][11][12]. In contrast to water ice which, under normal conditions, is an associated substance with strong tetragonally directed cooperative H bonds, monoatomic alcohols in the condensed state are viewed as associated objects with moderate H bonds and a chain-like structure [1,4].…”

“…The single methyl group CH 3 of the methanol molecule is bound to the hydroxyl group OH. Among the primary alcohols, methanol has the shortest and most mobile molecule, which makes it a suitable object for modeling the properties of alcohols having more complex molecules [1][2][3][4][5][6]. The simple structure of the methanol molecule shows up most obviously in its properties [2][3][4][5][6][7][8][9][10][11][12].…”

Thermal conductivity coefficient k(T) of two crystalline (orientationally-ordered and orientationally-disordered) phases of pure methanol (at temperatures from 2 K to T m , T m is the melting temperature), CH 3 OH + 6.6 % H 2 O glass from 2 K to T g , T g is the glass transition temperature and a supercooled liquid from T g to 120 K has been measured under equilibrium vapor pressure. The dependence k(T ) is described approximately as a sum of two contributions: k I (T) describing heat transport by acoustic phonons and k II (T) -by localized high-frequency excitations. The temperature dependences of the thermal conductivity of primary monoatomic alcohols CH 3 OH, C 2 H 5 OH, and C 3 H 7 OH in the glass state have been compared. Different mechanisms of phonon scattering in the crystalline phases and glass have been analyzed. The k II (T) has been calculated within the Cahill-Pohl model. There is an anomaly of the thermal conductivity of the glass state near T g (a smeared minimum in the k(T) -curve).

“…In the crystal phase methanol presents long one-dimensional chains of hydrogen bonds. 16,17 It has therefore been thought that something similar could be occurring in the liquid phase and be responsible for its peculiar behavior. Several numerical simulations [18][19][20][21][22][23] and neutron diffraction experiments [24][25][26] have produced data that support this view.…”

Monte Carlo simulations of liquid methanol were performed using a refined ab initio derived potential which includes polarizability, nonadditivity, and intramolecular relaxation. The results present good agreement between the energetic and structural properties predicted by the model and those predicted by ab initio calculations of methanol clusters and experimental values of gas and condensed phases. The molecular level picture of methanol shows the existence of both rings and linear polymers in the methanol liquid phase.

Advances in technology are rendering some of these difficulties less restrictive. In addition, in recent years, the power of powder diffraction techniques has been greatly increased so that it is feasible in many cases to obtain detailed crystal structures by this means. 9 This is particularly valuable, for example, for samples of small crystals embedded in an amorphous matrix, as is the case for many ceramic systems. Other advances in X-ray diffraction procedures allow electron
