Group values previously evaluated to adjust for temperature of phase changes are updated for aromatic compounds in view of recent experimental data. The new group parameters have been evaluated on the basis of their consistency in providing appropriate temperature adjustments to phase change enthalpies at T = 298 K as evaluated by a thermochemical cycle. This evaluation provides transition temperatures and about 1000 heats of fusion, 700 heats of vaporization, 500 heats of sublimation, and about 50 other heats of transitions for about 30 polyaromatic hydrocarbons and 1100 other molecules consisting of C1-C57 organic compunds, organometallics, inorganic compounds, and ionic liquids taken from about 900 references.","PeriodicalId":16783,"journal":{"name":"Journal of Physical and Chemical Reference Data","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49109417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These consensus estimates, in combination with measurements made in accordance with ITS-90, are an important alternative to primary thermometry for those requiring accurate measurements of thermodynamic temperature. Since 2011, there has been a change in the definition of the kelvin and significant improvements in primary thermometry. This paper updates the ( T − T90) estimates by combining and analyzing the data used for the 2011 estimates and data from more recent primary thermometry. The results of the analysis are presented as a 12th-order polynomial representing the updated consensus values for the differences and a sixth-order polynomial for their uncertainty estimates.","PeriodicalId":16783,"journal":{"name":"Journal of Physical and Chemical Reference Data","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43166116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Common derivatives of monofunctional compounds, such as trialkylsilyl, acyl, perfluoroacyl, oxazoline, and nicotinyl derivatives, are also discussed. The behavior of these under mass spectrometry (MS) conditions is determined, structures and stabilities of product ions are considered, and the ions of diagnostic power in their EI spectra are highlighted. Characteristic dissociation pathways for specific structural elements and their application for spectra/structure correlations are presented. Fundamental approaches for identifying unknowns are given. The advantages and limitations of EI-MS are emphasized. This knowledge is the key for successful applications of the exceptional capabilities of EI-MS for initial structure elucidation and then reliable structure determination of unknowns.","PeriodicalId":16783,"journal":{"name":"Journal of Physical and Chemical Reference Data","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48859697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental data in the range of temperatures from 215 to 444 K and pressures up to 35 MPa form the basis of the new equation. In this range, expected uncertainties ( k = 2) of the new equation of state are 0.07% for vapor pressures at temperatures above the normal boiling point temperature [Formula: see text], 0.2% for vapor pressures at lower temperatures, 0.05% for liquid densities, 0.15% for vapor densities, 0.1% for saturated liquid densities, 0.05% for liquid-phase sound speeds, and 0.08% for vapor-phase sound speeds. The new equation is valid at temperatures from the triple-point temperature (165.75 K) to 450 K and pressures up to 100 MPa with reasonable uncertainties outside the available range of data because it fully extrapolates with correct physical behavior to higher temperatures and pressures as well as to lower temperatures.

The negative ion properties of many elements in the main groups of the Periodic Table were well known in the late 20th century. However, our knowledge of the atomic negative ions of transitional elements, lanthanides, and actinides was completely lacking or largely rather qualitative at that time. Substantial progress both on experimental and theoretical sides in this subject has happened during the last two decades. New developments in the experimental methods that yield accurate electron affinities are described in this Review. Based on the previous reviews, a survey of the electron affinity toward the completion of the Periodic Table is presented. A set of atomic electron affinities and energy levels of atomic anions is recommended.","PeriodicalId":16783,"journal":{"name":"Journal of Physical and Chemical Reference Data","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48883816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The highest deviations found are due to the disagreement between the data obtained from different sources and not to an inadequate mathematical form of the correlation model.
