Introductory information
========================
Files included in the data deposit (include a short description of what data are contained): 

1) MB_GC_all.xlsx
2) MB_AT_all.xlsx

Explain the relationship between multiple data sets, if required:
Each dataset represents data at two ionic strengths for a different dye and polynucleotide combination at a binding ration of DNA base/dye of 3.


Key words used to describe the data:
Absorption Spectra, circular dichroism spectra, linear dichroism spectra, linear dichroism spectra, thionine, methylene blue, azure B, DNA, alternating polynucleotides

========================== 
Methodological information
==========================
A brief method description – what the data is, how and why it was collected or created, and how it was processed:
Absorption, circular dichroism, linear dichroism spectra were collected for phenthiazine dyes with different DNA polynucleotides to study binding interactions and mode at high binding ratios.

Instruments, hardware and software used: 
Absorption spectra were collected on a Cary100bio instrument.
Circular dichroism were collected on a JASCO instrument.
Linear dichroism spectra were collected on a JASCO instrument adapted with a Couette Cell that was constructed at Chalmers University of Technology, Gothenburg, Sweden.

Date(s) of data collection: 
1998 - 2015

Geographic coverage of data:
Newcastle University UK, and Chalmers University of Technology, Gothenburg, Sweden.


Data validation (how was the data checked, proofed and cleaned):
Data were zeroed where necessary.
Replicates at different concentrations were collected and checked against each other for consistency.

Overview of secondary data, if used:
NONE
