I would very much appreciate if somone could kindly show me how to finnish off what appears to be a simple formatting problem. Nearly there, but the last step has beaten me!
'ref' is what i want and 'ofmf' is the 'script' output.
Just a question of placing the 'mix ratio' character string immediately above the first data column and pushing the cell array one column to the right above the matrix. The number of columns and rows are unknown.
(Apologies for the messy data input!)

Eliminiating the newline character from the ‘Mix ratio’ fprintf statement:
fprintf(fileID,' Mix ratio');
produces:
Mix ratio *H HO2 *H2 H2O H2O2 *O *OH *O2 O3 H2O(S)

Is that what you want?
Writing it to a table and then using writetable would be easier, however that would not work in R2017a, because only valid MATLAB variable names were allowed as variable names then. The ability to use variable names such as you want was introduced in R2020b (if I remember correctly).

Jeepers, i missed that!!!
Just had a hunch it was possible with my outdated version.
This is the easiest solution to my problem and take note of your advice.
The other contributions are also much appreciated and will undoubtedly widen my understanding by different approaches. Thanks guys :)

I would suggest that you use compose as it makes it easier to create rows of data. If you use a "" quoted string for the format instead of a '' quoted string then the output of compose() would be a string() array that you could then strjoin with newline and fwrite the result.

See the attached modified script and resulting .txt file.
The file-writing section is reproduced here:
prodNums = length(prodNames);
fileID = fopen('ofmf.txt','w');
fmt1 = [repmat('%15s ', 1, prodNums), '%15s\n'];
temp = [{'Mix ratio'} prodNames];
fprintf(fileID,fmt1,temp{:});
fmt2 = [repmat('%15.7e ', 1, prodNums), '%15.7e\n'];
fprintf(fileID,fmt2,[of,frac2d].');
fprintf(fileID,' **************\n');
fclose(fileID);
