FTIR spectroscopy can provide insightful information in the microstructure for different plant taxa. Cuticles is a waxy protective layer that covers plant leaves and stems to prevent loss of water. Its constituted waxy polymers are generally well-preserved in plant fossil, which can be used for functional group analysis.
DIA-NN is optimized for processing of large-scale experiments. It supports DIA-based profiling of PTMs, such as phosphorylation and ubiquitination, new technologies such as Scanning SWATH [36] and dia-PASEF, [37] and can perform library-free analyses (acts as a database search engine).

This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
The database can be searched by entering one or more of the following parameters: chemical name (is possible to request partial or full matching), molecular formula, number of different types of atoms present in the molecule (as a single value or as a range of values), molecular weight (as a single value or as a range of values), CAS Registry ...
Fourier transform infrared spectroscopy (FTIR) [1] is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range.
OpenChrom is an open source software for the analysis and visualization of mass spectrometric and chromatographic data. [4] Its focus is to handle native data files from several mass spectrometry systems (e.g. GC/MS, LC/MS, Py-GC/MS, HPLC-MS), vendors like Agilent Technologies, Varian, Shimadzu, Thermo Fisher, PerkinElmer and others.
There are two main approaches to two-dimensional spectroscopy, the Fourier-transform method, in which the data is collected in the time-domain and then Fourier-transformed to obtain a frequency-frequency 2D correlation spectrum, and the frequency domain approach in which all the data is collected directly in the frequency domain.
