NIST DART-MS Forensics Database (is-CID)

Data provided by  National Institute of Standards and Technology

The NIST DART-MS Forensics Database is an evaluated collection of in-source collisionally-induced dissociation (is-CID) mass spectra of compounds of interest to the forensics community (e.g. seized drugs, cutting agents, etc.). The is-CID mass spectra were collected using Direct Analysis in Real-Time (DART) Mass Spectrometry (MS), either by NIST scientists or by contributing agencies noted per compound. The database is provided as a general-purpose structure data file (.SDF).

Hydrogen-Deuterium Exchange Mass Spectrometry (HDX-MS) Centroid Data measured between 3.6 degrees C and 25.4 degrees C for the Fab Fragment of NISTmAb

Data provided by  National Institute of Standards and Technology

The spreadsheet file reported herein provides centroid data, descriptive of deuterium uptake, for the Fab Fragment of NISTmAb (PDB: 5K8A) reference material, as measured by the bottom-up hydrogen-deuterium exchange mass spectrometry (HDX-MS) method. The protein sample was incubated in deuterium-rich solutions under uniform pH and salt concentrations between 3.6 degrees C and 25.4 degrees C for seven intervals ranging (0 to 14,400) s plus a control sample that simulates a Fab Fragment immersed for infinite time in D2O.

NIST Computational Chemistry Comparison and Benchmark Database - SRD 101

Data provided by  National Institute of Standards and Technology

The NIST Computational Chemistry Comparison and Benchmark Database is a collection of experimental and ab initio thermochemical properties for a selected set of gas-phase molecules. The goals are to provide a benchmark set of experimental data for the evaluation of ab initio computational methods and allow the comparison between different ab initio computational methods for the prediction of gas-phase thermochemical properties. The data files linked to this record are a subset of the experimental data present in the CCCBDB.

Mass spectra of sulfonephthalein pH indicator dyes and their impurities

Data provided by  National Institute of Standards and Technology

Sulfonephthalein pH indicator dyes have historically been noted for impurities originating from the synthesis process which lead to batch to batch differences in pH measurements. Uncertainties up to 0.1 pH units have been attributed to impurities in these reagents.

NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP) Version 9 - SRD 23

Data provided by  National Institute of Standards and Technology

**NOTICE: THIS VERSION OF REFPROP (9.1) has been superseded by Version 10: https://doi.org/10.18434/T4/1502528 ** NIST Standard Reference Data 23 contains revised data in a Windows version of the database, including 105 pure fluids and allowing mixtures of up to 20 components. The fluids include the environmentally acceptable HFCs, traditional HFCs and CFCs and 'natural' refrigerants like ammonia. Version9.1 REFPROP 9.1 has replaced the NIST 12 and 14 databases.
